What is your philosophy of dentistry? How do you want patients to feel when they leave your office?

That patients become more knowledgeable about their oral healthcare. Patients are treated in the most respectful and honest manner, I like to feel that I have reduced their anxiety about oral surgery.

What do patients get from your practice that they wouldn’t get somewhere else?

The ability to fully reconstruct a patient from ill-fitting dentures to the comfort, confidence, look and feel of real teeth with dental implants.

What do you like most about dentistry? What do you like least?

I love what I do each and every day. Making patients feel relaxed and comfortable is my goal.  The relationship we develop with our patients is so rewarding.  My least favorite aspect of dentistry is the dealings with the insurance companies to obtain medically necessary approvals for my patients. It is a constant battle to convince insurance companies to put the patient’s needs above their own.

Patient Review by deborah b

Dr. Mundiya and Staff helped myself and my Mother during her visit. My mother has Alzheimers - doing anything "routine" is a process . I was so nervous going in, thinking it's all going to be s*@t show! I must say it wasn't nearly as bad a I thought it would be! From taking the x-ray to having her tooth extracted, it all went smoothly. The staff was compassionate and patient as was Dr. Mundiya. He told me the results of the X-ray and what the extraction would be like straightforward -that is such a help when already dealing with an alzheimers patient! I would definitely recommend this office.
