“Amazing staff, technicians and dentist. Very friendly and super helpful. Absolutely don’t make you feel bad about the state of your teeth and are more than willing to work on a care plan with you. 10/10 definitely recommend.”

Jeff Sienkweiz​

“Dr. Kostides and his team are outstanding!!! I've had many dentists in my almost 60 years, either because of location or not caring for their care. However, I've been with Dr. K for at least 10 years because they ROCK!!!!! They are so thorough, professional, truly caring and so friendly. It doesn't get any better!!! Plus, he saved me money by providing great alternatives. Thank you, Dr. Kostides, for continuing your and your staff's stellar service.”​

Diane Sanders​

From the time I entered the office until I left, I could not have been treated better. The office staff, as well as the clinical staff are friendly, professional, and extremely competent. Dr. Kostides is very easy to talk with and his examination was very thorough as were his explanations during the examination. This was my first visit and I left confident that I will be getting great care.”​
