Excellent care

Awesome staff, all really friendly and professional. I've already recommended it to several friends and coworkers.

Dr. Darter and staff are amazing, they truly care about there patients. This is the best place to come for your allergies and Asthma

Thank you! Your staff is wonderful. Very professional, knowledge and always will to answer any questions I have. No matter how silly they may be!

Very thorough and informative. Nice employees.

It was a very pleasant experience

Everything was great. I'm glad I scheduled the appointment.

I saw you PA Rebecca. She was helpful, thorough, knowledgeable, and for the first time, gave me hope that we could figure out my allergy problem! I am so thankful and would highly recommend!!

From the front desk, to the nurse to the Dr. Everyone was so wonderful, polite, and considerate of our time. The Dr. was thorough and did a fantastic job educating me on my daughter's allergies. Everyone seemed to genuinely care about my daughter. Kisha was great... drew blood on a baby in one quick prick! Awesome. Already called my sister in law and recommended she bring her family to y'all! Thanks!

Nice and professional. Every staff member I spoke with was helpful and personable. Short wait times.

I can't say it's a pleasure to go to the doctor, but I always feel like I'm respected and my opinion is listened to. My treatment is on spot and I know I'm well cared for, even with a rare syndrome.

I liked the nurse practitioner I saw. However, she should type out instructions for the patient.

I am feeling much better.

First, I did not have to wait I was seen shortly after I arrived. Second, Kisha not only is very knowledgable , but explained everything step by step before doing her procedures. Finally, Dr.Bellak was very explisite, understanding and attentive. The three ladies from the front office were also great, they explained all contracts explicitly.

Diagnosis and treatment by Elisa were right on target. Within 48 hours of starting antibiotic, productive cough is gone. I appreciate Elisa listening to my concerns, discussing and educating me as to why she chose that antibiotic over another, and ordering the appropriate tests. I always find Elisa to be courteous, caring, and professional on each visit. In addition, all staff encountered on each visit are always helpful, smiling, and courteous to me. I very much appreciate that, especially when I am feeling poorly. Thank you for good and competent care on each visit.

Staff are friendly, my doctor's knowledgeable, and my nurse keisha is cute....

Really Dr Ballak was one of the best Dr experiences I've ever had. He truly listened to my long and confusing history of allergic problems and gave me so much of his time and attention and explained everything so thoroughly. You don't get doctors like that everyday. Thank you!!

Dr. Bellak and staff are absolutely wonderful.

We were very impressed with the efficiency and professionalism of everyone we dealt with. Everyone was patient and kind. They reassured my son throughout all the testing. The questioning was thourough and diagnostic. We were agreeable with the findings/conclusions.

Only thing I don't like is the wait.

Positive and friendly staff and made me feel comfortable.

Freaky fast doctor visits these folks are the Jimmy Johns of Allergies. Seriously the visit was great as usual.

Everyone was excellent and patient with my five year old

Courteous professional service as always.

This appointment was much smoother than last time and quicker! Thank you for taking care of my babies! We appreciate you!

Doctor Bellak and his nurse Kisha were both amazing!

Very thorough and great explanations.

My visit was very pleasant and the staff were wonderful.

Very professional. I felt I was obtaining real answers and that there was a genuine concern to find the solution. I had been told by more than one person... if you go to an allergist.. they find an allergy and you will have to get shots. You have proven that is not always the case.

Loved that you got me back to the room promptly. Everyone was very pleasant and knowledgeable. I'm glad I came here, and excited to get help with my allergies!

Almost zero time spent in the waiting room, got right in when my appointment was scheduled. I was surprised I could get a head CT scan right then there in the office, very convenient and saved me another visit. Knowledgeable staff answered all the questions I had.

Explained my asthma action plan well and explained solutions to my irradiated skin which helped greatly.

Dr Darter and her staff are great !

The staff was courteous and professional. Dr. Bellak was thorough - even reading my Registration form to be sure he addressed all my concerns. I would definitively recommend Oklahoma Institute of Allergy and Asthma to anyone with allergies or asthma.

First visit went well. Dr. Was very patient and answered all my questions ..

The doctor took the time to fully go over everything I had a concern about. Very thorough and appreciated the attention to detail on everything I said regarding my symptoms.


Dr. Darter is the greatest. She always gets to the bottom of issues presented to her. I appreciate her staff as well. Preston feels secure & has great amount of trust for Dr Darter. We are very fortunate to have a physician here in OKC to help so many affected persons.

I was very pleased with Dr. Bellak and staff! I'm hopeful this will get me the relief I am in need of! Thank you

Really love the Yukon office friendly and caring.


Doctor was patient to answer all of our questions.

Very professional, caring, relaxed enviroment.

I was the 4th patient of Dr. Amy Darter about 14 years ago, and she is still my doctor. She is a well educated, professional and compassionate doctor. The only reason that I would not go to her is because she was no longer practicing in Oklahoma, or I was not physically able to get to her offices. Doctors Darter is EXCELLENT physician and I thank God for her.

Great experience, couldn't have a better team taking care of me physically and monetarily ( savings on medications ). Thanks Again

We love Dr Darter's office. BTW, got this survey Afte our visit two weeks ago and thought it was asking if I wanted to take the survey then, and since I was on the go, I hit no, and the. realized it was asking if I recommended Dr Darter!😁 Tried to send a message to change but got that back. We love your office.

Good visit. Good doctor. Good staff. Thanks to all & God bess!

Staff was very good with my son and did a great job keeping him calm while doing testing. No wait either, which was great.

Our appointments went well from the time we checked in until the time we checked out. The only thing I didn't appreciate was a lady named Stephanie (I think) calling me several times about our insurance. I told her we had insurance and it was working as I had just took my daughter to another dr. She told me again it wasn't and threatened me I'd be billed w/o insurance and have to pay for the full visit. She called me again then I called our insurance and figured out the problem. I tried to call her back but she was busy and never called me back like I was told. If she would have just talked to someone at bcbs instead of using the automated system she would have found out they were having a glitch and all crest bcbs accounts would be fixed within 24 hours.

We were not given any discharge information or instructions. The girl who gave us the information on the medication we were discharged on clearly didn't know what she was talking about. The prescription sent to the pharmacy was messed up then messed up again. I was not confident at all in the dosage and time length of the prescription as well as the reason we were being givin the medicine. What I was told in the office was not what the prescription said when I picked it up. Still had many questions when I left the office.

Dr. Bellak has been concerned and helpful.

Dr. Bellak and the staff at OK Allergy take time to talk to me and work out a plan that we both agree on. They are always kind and inviting. I know I will be well cared for each time I visit.

It was a very good experience, always is.

Nice staff

GREAT STAFF! Dr Bellack was very infornative and friendly

The doctor was very professional and courteous. She took the time to answer all of my questions. The appt did not feel rushed, and I really appreciated that. I would definitely see this doctor again. The front desk people were very nice and professional as well.

Good visit

The wait was much shorter than I had experienced in the past. I very much appreciated that, since it has always been an issue for me, either having had a long wait in the waiting room and then again in the exam room. Thank you for whatever changes were made to implement that.

Happy with my experience.

I have shared with my friends and one made an appointment with Dr.Darter and your clinic. I am always very pleased with the way the doctors and staff conduct business. Thanks


Thank you for the wonderful service you provide us, Dr. Darted is amazing with our 4 year old who is allergic to a lot of things. We are figuring out how to manage and make his life more normal!

Friendly Courteous Helpful I will refer to others as I was referred for these reasons

The doctor was thorough in going over my daughter's symptoms and potential treatments. She explained everything clearly. I loved that she spoke directly to my daughter about her condition. The office staff was friendly and helpful. I hope that our follow up visits are just as pleasant and productive!

I've had many appointments and I'm always happy with whoever I see there. Usually they are very thorough and I'm thankful for that. Always a courteous staff and people who are very caring. Wish I could see Dr. Darter, herself a little more often.

Katie Ellis is fabulous! From her bedside manner to her detailed records which track my son's history, progress, and plan for improvement...she is an all-around excellent caregiver. The front desk staff is also friendly and efficient.

I have been a patient over ten years. I have never had a bad experience.

Very friendly and helpful, thank you!

Very pleased with kisha and dr Bellack. We drove three hours for allergy testing and the first thing we heard when entering the room was the amount of money needed for the test. It would have been nice to know all of this prior to the apt so financial arrangements could have been made.

Visit today was good. Katie is amaking and always very helpful.

Had only a 4 minute Lobby wait. Dr Bellak was immediately in the room and gave us his undivided attention and explained a new treatment plan thoroughly. Ms Keisha came in and explained treatment again to my 7 yr old and gave it to him in terms he understood. A wonderful visit!

My experience at the clinic was fantastic as always. When I called for an appt., I was accommodated the following day. Leslie was super. She listened to all my complaints & knew exactly what to do for me. All the staff was courteous & most helpful, yet very professional.

This office is a very professional top notch staff courteous polite and professional.

They spend a lot of time with us and answer my questions without making me feel dumb. Thank you.

So appreciate the thoroughness with which Amy Darter & Elisa Thompson have approached my case. I believe they both are on the right track & I'm so grateful. Excellent clinic, excellent doctors!! Thanks!!

Everyone is always very kind and takes time to explain everything to you carefully.

The communication has not been great. Phone calls are not returned in a timely manner and it's taking a week to get a simple test result back.

Love your office!! I had a great recent experience where they got me in the same day and called me back with lab results immediately! Thank you Leslie and staff!! Hayley is always so helpful too!!

Great place

Staff is very friendly and always very helpful.

Very kind, friendly, and knowledge staff.

Staff is always friendly/helpful. And I trust the advice from doctors, who are willing to answer all my questions.

Friendly, and thorough with finding out your history!!

Very professional and friendly staff.


Glad to finally have a treatment plan that works. Not only do I have relief for my rhinitis but I know it's environmental not allergic and I can stop wasting money on OTC meds that don't work. Dr Bellack is great.

The staff is very friendly and professional. Any medical issues or concerns I may have are always addressed.

Courteous staff, and my P.A. Is super easy to talk to.

Went the extra mile

Love the fed and nurses there. They have wonderful advice and are very nice.

I arrived early and was taken very quickly even though I expected to wait until my actual appointment time. Everyone is always so warm and friendly there and Dr. Bellak is my new hero for diagnosing my condition! Kudos all around!

Elisa is just a phenomenal provider. She takes time to listen, always tries to come up with different options and is so caring.

You guys were great! Helpful and thorough.

Girls are very nice and made if less stressful for a 10 year old.

I have been coming for nine years and everyone has been wonderful

Timely, efficient, informative, caring, solid recommedations.

Thanks for seeing me so quickly

Dr. Bellak is one of the best doctors I've ever had. Oklahoma is very lucky to have him.

Everyone was friendly and professional. I was a little nervous about my appointment but everything went great.

The staff was friendly.

Great care on each and every visit.

I just don't like doing a breathing test 2 times in a visit

Took quality time to listen and explain everything to me. Made appropriate understandable recommendations.

I am very satisfied with my care. The Dr. and PA's ,nurses,front desk ladies do a great job!

Staff were excellent and cared about me. Very thorough in their questioning illustrating great care.

Friendly and knowledgeable. Felt cared for as a new patient.

Rebekah did a very good job. She listened to our concerns and addressed those issues promptly.

I was so pleased with Dr. Elissa! She went above & beyond to thoroughly understand what has been happening in my situation. She took the time to explain and make sure I understood all that was happening during my office visit. I look forward to continuing my care with her & good results. Thanks so much to everyone who assisted me today!!

Great visit and staff!!

The dr was great and I love that she was strait to the point!

Rebecca is outstanding. Would recommend her to anyone needing allergy services.

Friendly nurses and great servicd

Elisa Thompson is great. The new NP she was training was good too. The nurses are great. All my questions were answered. Thanks for all you do to help me.

Becca was perfect. I will highly recommend her.

Always a great experience everyone is very helpful and has a great attitude.

Prompt; thorough; knowlegeable; efficient

Great clinic with great staff! Been going there for almost 3 years and feel lucky to have such competent and friendly people to deal with!

I'm a new patient and was treated wonderfully by every staff member I've encountered. Such a warm and friendly environment. I'll be back!

Came in for retesting after 2 1/2 years of shots. Everything was organized and efficient. Love the P.A. Elise. She didn't seemed rushed. Explained everything and patiently answered all my questions. Great staff all around.

All good

Great first experience! Everyone was so nice and the doctor explained everything well and spent a lot of time with me. I would highly recommend anyone to your facility!

First visit there, everyone was incredibly nice, I would go back if I needed to. As much as I dislike going to doctor appointments, this was easy and the fact that everyone was friendly made it bearable. Thanks guys!

Absolutely loved the experience and am excited to start shots so that I can feel better!


Thank you for taking the time with us!! Staff was very helpful and friendly!!

The doctors are very knowledgeable and have helped improve my symptoms so much!

Thank you for your great service. I am very happy to receive your service and expertise. Very good doctor and staff.

I'm pleased with the medical care and the business operation as well

I arrived 20 minutes early and my appointment time was prompt and right on time. This was important to me because I scheduled my appointment during working hours in my lunchtime.

Very knowledgeable and friendly.

Elysa was very explanatory of results of testing and what steps to take next. Also noticed something outside of allergies and raised it to my attention. Thank you!

You were very helpful with my issues and also very informative. I learned plenty of new things at the visit that will help with my quality of life. I'm on some new meds now and already feeling better just after a few days. Thank you.

Each visit has been an enjoyable expierence. I do not find that very often when visiting a medical facility.

I had a very good experience, and Dr Darter was very professional and took the time to make me understand what was happening with my problem.

Everyone is always helpful and nice. The only issue I have had is feeling I'm not paying on my balance which I am so I feel as if I'm required to show proof every time it comes up. If I'm not paying quick enough then let's discuss it but I'm trying to pay 100.00 every time I'm in for a shot. The balance is around 300. Now. Outside of that your place of business has been great.

Staff was very friendly. Got us in and out quickly! Helped calm my daughters fears and worked really well as a team to get some testing over quickly before she could even cry!

Rebecca was very helpful and I learned A lot about my medical issues.

Dr was thorough and my meds were called into the parrmacy in a timely manner.

The entire process was timely and very thorough. I didn't have to wait and everyone was very nice. Would recommend to everyone. Great place!

Great and friendly staff. Per usual, Dr. Bellak was thorough!

Thanks for the checkup

Saw Dr. Darter & she ROCKS!

Great care, very pleased.

Rebekah is awesome!

I'm so happy I found this clinic. They are so sweet plus they stop and listen. I'm very satisfied and highly recommend Dr Darter and her crew! Every chance I get, I let people know this is the place to go!

Rebecca is great! Thank you.

Elisa was so gracious and compassionate today when she heard about my breast cancer diagnosis. I so appreciate the support she gave me and the Medical care she administered! Thank you Elisa

OIAA has really helped me to live a life without suffering from allergies.

Professional and informative. Helped me with everything I went there for. Friendly staff. Dr was great!

Saw Dr. Bellick as new patient. He was very willing to discuss my medical history and make plans for acessasing my status. Looking forward to making plans to manage my allergic & asthma.

I have been healthier and my allergies managed better in the last 2 years than the past couple of decades.

Lots of good information.

Always friendly. Explain process of shots well.

Dr. Belak was awesome! Very thorough, explained everything, and above all he listened! He broke everything down into Layman's terms instead of throwing out a much of things I couldn't understand. I've already recommended him to my friends and family. The nurse who took my blood busted a couple veins before finding a good one. At one point she even asked me if she should stop and if I wanted to go some place else to get my blood drawn. I opted to have her try one more time and she was successful. She was very very nice, but I've had my blood drawn multiple times and never had his happen. It's possible this could be the result of my veins and not her skills though! Overall, it was a good experience.

Your PA (Ms Green) is an awesome health professional! She has been courteous, respectful and attentive to my health needs. She is very knowledgeable about my health concerns and is an asset to your program. My only criticism is that during the past 4 years or so of being treated at your facility, I've seen at least 4-6 PAs as they don't seem to stay at this facility long. But, each PA I have dealt with has been extremely knowledgable.

We really appreciate Elisa Thompson taking the time to answer all of our questions and spending time going over our test results with us! Thank you! It's been super challenging going through this process with food allergies and we're grateful to have her helping us get through it!

This whole office is amazing! I highly recommend them to everyone!

Very helpful, friendly and listen


Your staff, office and Dr's are amazing! Very friendly and they help with any concerns you may have! Will definitely recommend to others that have the same issues! So happy I found you! Nicole Andersen

Katie is great!

Everyone did a great job. Everything was on time. Good experience

I was in and out quickly. I am still waiting to see results of all prescribed medications.

I arrived at 4:15, and I walked out at 6:00. Later arrivals were taken back before me. The nurse did apologize, but she should have confirmed the patient's name before taking her back.

You guys have a great staff.

I appreciate the care I receive here. I did not feel rushed and felt I could ask all the questions I needed to. I am confident in the team here and feel my needs are important to them. Thank you.

Everyone was very attentive and spent extra time trying to find the best way to meet my individual needs.

Very professional and knowledgeable.

Elise was great and I was pleased with my visit

Thanks for being so sweet and gentle wth Elijah and encouraging during his food challenge!

Dr. Darter is great! She knows what's she's doing and is helpful. Today she seemed in a hurry. We waited over 30 min in our room to see her which is very hard with little children. That is very frustrating for us and everyone else that has to hear them for the 1.5hrs we were at the office.

Your staff is amazing and you do stand up to your reputation. I recommend you to anyone I see suffering from allergies or asthma. Thank you for helping me get back to living!

Everyone was very helpful and knowledgeable.

I like the way everyone tries a few things at a time to see what works before trying something else.

Staff was very friendly!

Great support and attentions to details. I felt valued as a person.

Dr. Darter and her staff were great! Got me in quick. So knowledgeable an helpful!

It was Awesome!

I'm always very pleased with Dr. Darter and the entire staff. Her PA's are very helpful and informative as well. I hate being herded through quickly and being another number. You are not th like that at all and it's a genuine blessing! You all always take the time to listen and are very thorough. It's great to know that a doctor's office still cares more about helping the patient!

The nurse Keisha was awesome!!! She made a very high stressful appointment much more bearable. I'm super thankful for her. She went above and beyond to help our food allergy testing go smoothly and with few tears from our 2yr old! Thank you Keisha!!!

We love coming to our allergy specialist and get great service from the staff! We were upset to find out that our normal PA we see had left and now we have to use someone else.

Rebecca and her nurse do a wonderful job every time I have been in. They are very thorough and always encourage questions. They will always explain anything that is not clear and are very patient.

On time

The wait wasn't long this time and I love Rebeccah. She is so personable and takes the time to really listen.

Loved new office staff, first time I felt like they knew what they were doing and not reading a script. NP Elisa is awesome.

Tyler is awesome

Summer is awesome!

Extremely positive experience. Staff was great and Dr. Bellak was knowledgable, took time answering my questions and was very personable. I felt that I left the office with exactly what I needed! Thanks!!

Friendly office , very benefit and accommodating staff.

OIAAI has greatly improved the quality of my life. I'm no longer chronically sick with upper respiratory illness. I love the walk in system for allergy injections. Dr. Darder is a wealth of information and is extremely helpful. I trust her completely. She has helped me in other areas of my health in addition to my allergies. I would highly recommend her and the friendly and professional staff!

I was extremely ill when I initially visited OIAA. My asthma was beyond being out of control. I was chronically ill, and treating symptoms from one infection to the next. My life and activities revolved around my illness. I no longer made plans, even short term due to my health. The entire staff at OIAA is absolutely invested in assisting me in regaining my health. I feel as though each member is part of my extended family. They are warm, engaging, competent. They go above and beyond to insure that my insurance provider is supporting my needs as well. The staff effectively communicates with me and assist in educating me on my condition, my options, and my continued progress. With the expert advice and comprehension treatment I have received from OIAA, I have made tremendous steps forward in my journey to become healthy and manage my asthma. I am so grateful to the nurses, office staff, and physicians that continue to devote their time and energy to help me and many others like me, in being able to live again. I have and will continue to recommend OIAA to anyone with similar health issues. I fell so Blessed!

Skin test, oral drug challenge and CT scan

Everyone was very friendly. My son & I felt very comfortable & welcomed

I really was glad that Laura took the time to show both myself and my 5-year-old what she would use to do skin testing and how it would work. That helped to put our minds at ease. Dr. Bellak was very nice and explained things in great detail. I was very impressed and will definitely bring my other children when they need testing and will recommend to others!!

As Always, very pleased with every aspect of the visit. The only group of Dr's and facility that actually seem to be interested in helping. Thanks.

Staff was very helpfull and knowledgeable! I was in in out in good time and was well taken care of.

My daughter got same day appointment which I really appreciate. Rebekah was very good overall and I liked that she talked with Dr Darter. I truly value Dr. Darter's insights and diagnosis.
