Best dentist I’ve ever been to,great staff makes going to the dentist a real pleasure

Appreciate your help with Chelsea’s retainers. Thank you!!

Teeth feel great

Let you know what you did well? Everything your people are incredible Dr Frandsen is amazing what can I say I've had a great experience every time I've had to go and this is from someone who has quite the phobia of dentist. Every time I've been there, seeing Dr Frandsen and his staff has definitely helped release some of the fear of my phobia of dentist. Hallelujah!!! thank you Doctor Frandsen and you're wonderful staff

What a great experience, stopped by Doc Frandsen office to make an apppontment to have a tooth looked at that I had just discovered had a problem. The office person said give me a minute and we will have a look. Incredible not only looked but fixed it so I would be good till the problem could be permanently repaired. Thank you. Jim Foster

Best dentist team I have had the pleasure of seeing! Wonderful people!

Very thorough.

Very friendly, caring and professional!

I went in for routine cleaning and was rushed due to following Dr appointment. Tennille did an excellent job. She’s very gentle, yet thorough. Dr Heninger found small cavity that will take care of next visit. Always pleasant staff

The office staff is very professional and friendly. The Dental hygienist and the dentist were amazing!! Very friendly professional and they keep my smile Perfect!! They are just like Family!!

Good experience as usual. Very efficient, no wait time. Everyone is very professional yet welcoming and friendly

Very friendly and kind to all of us

Dr. Frandsen has been an excellent dentist for our entire family. He is genuinely friendly, extremely competent, and always thoroughly explains treatment plans. He is very accessible and has arranged out of state dental work when needed. If you are not totally happy with your dentist, like we were four years ago, make the switch to Dr. Frandsen and Dr. Heninger.

Clean and quick service. Everyone was friendly b

Friendly and efficient. Our dentist for decades.👍❤️😃

I like Dr. Dave he’s a straight shooter!

First visit since COVID-19. Was very impressed with the care and precautions practiced by every staff Member. Connie always does a great job cleaning my Teeth and is extremely gentle. Dr Heninger Performed a comprehensive examination and caught a very small issue that will be corrected soon. My wife and I enthusiastically recommend this office.

Great dentist and friendly staff. Always a pleasant experience!

The staff is always very friendly and efficient in what they do!

Service was very professional and personable. This office staff has done more in one visit than my previous provider did in several years. I highly recommend Heninger and Frandsen.

Best dentists and staff EVER!!! With them, it is actually a pleasure to go. They really truly do care about their patients and their questions and concerns!!

I appreciated the care with which I was treated. The hygienist and doctor wore gloves and face masks to make sure I felt comfortable in our health-challenged environment. Dr Franzen is a very caring and talented dentist and I felt like he was interested in my jaw problem and had some good ideas about helping me.

Your staff is always friendly and very professional. Dr Frandsen did a great job resetting my crown.

I got a bridge done last week and it’s super easy to check in and I really enjoy the Family warm feeling I get when I walk inside. The wait time is short the staff is really on top of things from the front desk to the back They instantly know soon as you walk in the door 🚪 there really happy to see you And they got these really nice bright smile win they see you 😃What I like a lot about this place I’m not getting a whole Lotta different smells the doctors and the nurses does not have any cigarettes smells on their clothes are on their breath they let you know what they’re doing and they explain things really clearly before they start and they listen to your comments before they start so if you have really sensitive teeth this is the best place to go. And they follow with the insurance wants so no surprises when you get your bill I also like when I get my receipt I get to see win mi next appointment is in my children’s appointments so I never miss an appointment it makes it so nice and when I do miss an appointment it is so easy to make another appointment my kids love Dr. Henegar and Dr. Francis I’m amazed how well they take care of my kids and their teeth have this amazing great smile my kids aren’t worried when they have a cavity because they know they’ll get taken care of which also means as a parent I still have a lot of work to do to help them out with that and when they train new people I have no concerns because Dr. Henegar and Dr. Francis trains them really well and they stay watched and any questions that they have they ask it before they work on your mouth so I’m always at ease regardless who works in my mouth I love this place I will never go anywhere else There’s no other Dennis in town that can’t compete as well as these two guys

Great dentistry and professionalism.. prompt scheduling w

I really like this office. They are kind and do a great job. Love Tenille and the work she does.

Very professional and they make you feel comfortable. Dentist visits are no longer dreaded.I enjoy my visits wit Dr. Heninger he’s honest and will tell you really how your doing with the upmost confidence and compassion. The staff are great send reminders for your appointments and so courteous. We refer all our friends.

I was blessed by the pleasant helpful staff and Doctor Heninger. Doctor Heninger checked, cleaned, and cemented my misplaced crown in thirty minutes. I was so happy for their help. Thank you!

Everyone is super friendly and very knowledgeable 🙂

Kind and caring staff, made me feel safe and comfortable.

I am thankful Dr. Henniger was able to fill my broken tooth, evenly file my lower teeth and answer my questions about the scar on the inside of my mouth, how long to wear my retainers, and make suggestions for the best way for cleaning and whitening teeth.

Always professional and courteous service!

It was an awesome visit. As always your staff was accommodating and friendly and my cleaning was done with the high standard that seems to be the norm at your facility! Thank you.

Always a pleasant experience!

The dentist I had been using for many years retired and I have been looking for some one new. Dr. Frandsen was highly recommend by a friend. I found the staff to be very friendly and professional. Dr. Frandsen was easy to like. He put me at ease by explaining his very thorough approach to providing excellent dental care. Dr. Frandsen also took the time to explain the reason behind everything he was doing or suggesting as part of my examination. At the conclusion of my visit, I felt very comfortable that I had found a great new dentist.

It's always a pleasure to visit your office. Well, as fun as a visit can be to a dental office! Thanks so much for taking good care of us

Dr. Frandsen is the best dentist of all time!

Dr. Frandsen was very friendly and made my visit very easy and painless. The staff is friendly and the facility was warm and inviting. Highly recommend.

Phenomenal!!! Very professional, friendly, and makes going to the dentist fun!!

The staff is always courteous, friendly, and professional. The Doctors are efficient and extremely knowledgeable in the performance of their dental jobs.

Dr Heninger has been my only dentist for a long time. He is always friendly, very competent & knowledgeable, and the office is spotless. The staff are equally professional, competent & friendly. It's a great office!

very good people enjoy ed my visit

Great staff. Every visit is top notch!

Such sweet people doing such a hard job...glad I found these awesome people to help me, but I've always had such rough experiences till now ... thanks!!!

Always a friendly staff. Taking care of my family for many years.

Very professional staff, doctor listened to my concerns and addressed each of them making sure i understood everything. I find most doctors/dentist lack people skills in this day and age.

Left a message while the office was closed. Got a call back and an appointment the next day. Tooth ache taken care of! Thank you!

Dr. Henniger took good care of me, as always! 😁

I was fit in on short notice on a holiday week, and my problem was resolved quickly

They are always so friendly and on time

Always the very best care and concern for your patients!

Great customer service and care. One of the best dental experiences I’ve had. Thank you!

Such great people, I’ll never go anywhere else unless I have to!

Whether having your teeth cleaned, in for your annual checkup or having dental work done . . . always a GREAT experience! A big thank you to the office administrators, the dental hygienists, the dental assistants and to Dr. Heninger & Dr. Frandsen . . . job well done!

Thank you for getting me an appointment so quickly when I lost a front filling. You are always so accommodating and friendly. I appreciate being able to always count on you when I need assistance. Thanks again.

Fantastic customer service! Very personable and I would highly recommended Dr. Frandsen. Thank you for everything you do.

Dr Heninger is kind and concerned about my health and comfort. Everyone on the staff is helpful and cheerful.

Everyone was very friendly and kind from the receptionist to the dentist himself. They never seemed to rush and were willing to answer any and all questions or concerns.

A great dentist. Really trust him.

I felt more comfortable in your office than any other I’ve been too, and that’s somehow factoring in the discomfited state I was in before my visit! Great job guys, thanks for all you do to be the best!

Taneal was terrific. She explained to me an issue I was having with my gums. She was very personable and I appreciate that. The gals at the front desk are always efficient and friendly. And doc....well he is the BEST!!

My tooth was aching and I was really happy to get in the same morning. Everyone treated me very kindly. Dr Henniger is a great doctor and I am very comfortable with his abilities and I know he is a friend. You can trust your teeth to his care.

Thanks for taking me in without an appointment while I was transporting another of your patients and helping to get “something” out of my teeth! I appreciate your time and talent. Thanks

Always a pleasant experience

You guys are the best. Been seeing Dave and Justin for over 25 years and could not ask for better dental care! John Heer

Short waiting room times. Friendly, knowledgeable, and professional staff!

Thank you for the great appointment. The staff are amazing. Connie is always friendly and wonderful. Keep it up!

Connie always does a great job. She’s efficient and friendly. She asks if I’m comfortable. Keep up the good work.

Tenille does a great job! I really like Dr. Frandsen. He is kind. He has a gentle touch which means a lot since I had dental trauma for years when I was younger. He actually gets me numb which is GREAT! Thanks to all at the office. Very friendly.

Dr Frandsen is the best! Thank you for taking such good care of my kids! They like going to the dentist now!

Dr Frandsen and all the staff were all great very professional and friendly

Great atmosphere! Kind, caring, professional staff! Worked with me to get an emergency appointment on short notice. Really like this office!

Very pleasant experience, 4 fillings, no pain.

I have always had excellent care at Dr. Heningers. Connie is great. Teeth clean and out in less than an hour.

Dr. Frandsen is so kind and thorough. He always explains what is he is doing and always makes sure all questions are answered. I will never go to another dental office!

Couldn’t have asked for a better experience! Everyone was so welcoming and kind and made me feel important.

Friendly and efficient. I didn’t have to wait long. Also very thorough without over prescribing treatments. I don’t get the sense that they push the most expensive solutions first that may be overkill relative to other, less invasive and pricey options.

I have a really sore jaw thought it might go away but it has not. I emailed you but didn’t hear back I probably need to get in soon to have it checked. Mike Kingston

I have always been treated well and after many years of care, I can say that Doctor Henniger is a good doctor and a good friend.

Great experience! Thank you!

I love the fact that my two boys love going to Dentist which is a huge improvement from other Dennis I have a place to play games so do not worry about waiting I love the fact that they ask questions and see what they can do different or better and honestly I’ve been going to Dr. Henegar and Dr. Francis for over a decade now and I am impressed how well they take care of me and my children and when they do a tooth filling I don’t know any other dentist in town That does amazing work that they do I’ve had family does complain about their dentist and I always send them over to Dokter Henegar or Dr. FrancisAnd the staff there are really sweet and super polite and they’re all really good at their jobs there’s definitely a place where me and my kids will always go and they help me with my insurance

The dental staff are excellent because they are knowledgeable, kind, respectful, and deliver the best dental care. I always leave their office feeling as though I have been to a spa for my teeth. We drive 600 miles (round trip) because we receive such wonderful care here and we love the staff—they are the best!

As usual we had a great visit. Dr Heninger and Connie did a wonderful job. We were in and out in appointed time, very thoroughly and all staff friendly and efficient.

I had a pleasant experience. Dr Henninger is the only Dentist I want to use ď

Everything was awesome! Thank you!

Dr Frandsen and Connie provide such quality care. My appointment was speedy, but thorough. You would not think of a dental office being calm and serene, but that is what I always feel when I'm there. Thank you for a wonderful dental cleaning and examination.

An excellent decision to come to Dr Frandsen! A lot of dental work lies ahead for us, but we trust it will be done well and in a timely manner. Thank you for being kind and patient with us, and for explaining each process so thoroughly.

Thank you for your thorough exams of both of us. The hygienists were professional and kind. The office is modern and very well equipped. Dr Frandsen took a good bit of time out of his day to explain my husband’s many dental issues with clear pictures, and gave us a plan to address them. I wish we had known about this dentist long ago, as the ones we moved from hadn’t taken very good care of my husband. I would recommend this dentist to everyone!

I changed dentists a few years back and I fill like family and have had wonderful experiences with every visit .😁

Going to dentist is not something one looks forward to. But Dr Heningers office is always friendly from the initial greeting with a smile, through the cleaning by Tenille who is extra gentle, and the final exam by Dr Heninger who is thorough and answers all questions. Tenille also is knowledgeable and answers questions and gives suggestions. The entire visit was pleasant

The wait time was minimal. The dental tech and doctor were very good at explaining what the images showed as well as the results of the exam and cleaning.

The staff was friendly knowledgeable and helpful. I am not positive what is going to happen Wednesday but I will be there. I understood what the dentist told me but wished for more detail. Overall, I think I am in good hands

I came into town hoping to get my tooth repaired due to an unexpected happening. I was pleasantly surprised and the receptionist got me in the very next day. Thank you SO much!! Tricia Hancock

Always gentle and kind. Very understanding.

Very inviting environment

I love this dentist. Both of the guys are wonderful. I grew up in Idaho. And I now live in Utah. I actually make a trip to make sure I can come here because they make me feel comfortable and take good care of me!

All the staff are very friendly and welcoming. Great service and on time. It doesn’t get any better than that

Love Taneal and all staff are very friendly

Dr. Frandsen & his staff were excellent in accommodating my emergent dental needs. He took time to educate me on all my options. Thanks to him & his staff I have a normal set of front teeth again! :)

My visit to see my Dentist and Friend are always a pleasure. Every one is so friendly and welcoming as soon as you walk in the door . I always have a pleasant experience when I have a set appointment. From all the staff to the Drs I would highly recommend them to anyone that needs dental care .

I just love coming to this office. Dr. Frandsen and his staff take the best care of his patients. I felt comfortable being at the dentist. He’s changed my life with trigger point injections to help my pain that comes from neuralgia. Grateful for such a knowledgeable and personable dentist. Highly recommend.

Very knowledgeable and personable dentist. My care has been fantastic for more than 25 years. His staff is great. You can't find a better dentist in Idaho Falls.

Dave and Justin and the entire staff there at your office are not only very professional and adept at what they do but they are also good friends which makes the whole visit that much better. I have referred several people in the past and will continue to do so. John Heer

The visit went very well, I am very happy with the way I am treated by the doctors, assistants, and staff.

I arrived at 3:20 for my 3:30 appointment. I was warmly welcomed, and my insurance information was promptly recorded. At 3:30, I was called back, and welcomed by Jennifer and Dr. Frandsen. After being comfortably settled into the examining chair, Dr. Frandsen answered all my questions and concerns and assisted me in feeling relaxed through conversation. He explained enerything he was going to do in a friendly way. The entire procedure took about half an hour for the numbing shot and the filling procedure -- a pleasant experience. I highly recommend Dr. Frandsen and his staff.

Absolutely the best. My wife was in extreme tooth pain and needed an emergency root canal. Dr. Frandsen and Sherry showed up to his office, at 8:00 pm, on a Saturday to accommodate us. Never once did we feel like it was a “bother” or “can’t they wait till Monday” or “I’d rather be doing something else” while we were there. Quite the opposite actually. He does excellent work and is always very professional and curtious. Thank you!!

Jax has never been a fan of the dentist until we came and saw Dr. Frandsen!

Great team. No more fears of going to the dentist.

It was a good experience overall. I also appreciate the extra effort to get me worked in before the end of this month.

I always enjoy seeing Dr. Frandsen. He always makes me feel good about my teeth. Most dentists will just bring up my crooked teeth, but will never comment on how good my teeth actually are. I’ve never had a cavity before. He always gushes over my teeth and actually makes me feel good about myself. I really appreciate that. I also appreciate that the hygienist doesn’t try to get me to talk while her hands are in my mouth. I love to talk and be friendly, but it’s so difficult during a cleaning. :)

Got me an appointment in a very timely manner and was very informative on what my dental treatment would need to be

Thanks for getting me in quickly!

Love Connie! She does such a good job cleaning my teeth! Dr. Henniger is kind and thorough. Been going to them for years. It’s a lovely office. The entire staff is kind and professional!

The cleaning was okay, but I experienced an awful headache afterwards.

I always get any questions about my dental health answered. Everyone is always gentle and caring, thorough and attentive.

Cleaning, Anesthesia, setting a post, mopping up and reschedule. Can't wait.

Exceptional. Simple cleaning, but appointment was EXACTLY on time and almost pleasant! ;-)

Great way of explaining everything and allowing me to make my dental choices. I've hated feeling pressured at other offices and really appreciate the care!

Great experience! This was my first visit there and starting with the front desk everyone was so nice. My hygentist was so great and did such a good job. Dr. Frandsen was also extremely nice, very thorough, and made sure all of my questions were answered. Would definitely recommend this office!

Kindness and understanding

Service was friendly and proffessional. Appointment was right on time. I felt very comfortable being there.

Connie did a great job

Great work. You take a bite out of my cavities

As always...I had a perfectly comfortable and relaxing experience. I highly recommend Dr. Heninger and his staff. Always a pleasant experience.

Dr. Heninger is always so kind and caring . He took great care of my needs

Twenty years and I have never been disappointed. Always prompt and responsive to my needs, always responsible and reasonable with my dental care.

My dentist recently retired. I was very apprehensive about finding a new one. My friend told me about her dentist so I made an appointment. I’m so glad I found Dr. Frandsen. He is great. Very kind, listened to my concerns, explained the procedure details and got me numb which has not always been the case throughout my life with dental procedures. Loved his hygienist, Tenille too. Overall, I had a great experience. Thank you!

Love you guys!! Dr Heninger cannot retire under I’m 6 ft under! Lol You are the best!!!

The appointment was on time and everyone was nice, it all went well, good job.

Dr. Frandsen and his staff are very knowledgeable and do a great job. I would highly recommend their office if you need a dentist in Idaho Falls.

Great dentist and great staff! Nice office space, too. Always a pleasant experience.

I was late for my appointment but they worked me in anyway. I would highly recommend them.

Always asking about problems and making sure I am kept informed on things that are being done. Problems are worked on right away unless more time is needed and is scheduled right away. Great place.

Connie is the best dental hygienist I have ever had in my whole life! She realizes the problems that I have since my cancer and is so gentle and fast so it doesn’t hurt so bad.

Very satisfied with our appointments today and yesterday. The office is spotless and the equipment state of the art. Dr Frandsen and the staff who interacted with us were kind, caring, welcoming and knowledgeable. They spent time explaining each process and treatment thoroughly. Thank you for making us feel comfortable and confident that we will have our dental needs met.
