Patient Reviews

I've been a patient of this office for over 20 years and have seen them many times. My wife and our 2 kids are also a patient of Dr. Kretz. Dr Kretz and his staffs are a true professional family dentist. I am extremely satisfied and impressed every time I set foot in their office. Their professionalism, welcoming smiles and the impeccable care I receive is what keeps me coming back. I strongly recommend to anyone who was hesitant about seeing the dentist to go see them

Can going to the dentist be FUN? At Dr Kretz's coming in the front door being greater by the staff just makes you feel good. I had my teeth cleaned. Quick, painless... Almost fun . My teeth and I are happy

Overall Rating

Amazing front desk, assistants, hygienist and Doctor .Dr.Kretz goes above and beyond for his patients and he makes you feel comfortable. You can tell they work as a team and get along very well. Everything gets explained from what treatment you need and why to the Financial part of it .I moved to New York and if I ever need anything major the thought of paying for a flight to go to Dr.Kretz is there. Definitely worth the flight for great service , Care and quality work . Don't question yourself and go see Dr.kretz !
