Q&A

Where did you grow up and what brought you here?

Lake Ronkonkoma, NY. I moved away for dental school and decided to return to my home state.

What do you love most about this area?

I love the four seasons, outdoor activities, professional sports that aren’t far away. I also love the American history.

What is your philosophy of care? I treat patients as if they were part of my family.

What is a quote you strive to live by? It’s not how others make us feel that is the most important in life but rather how we make others feel.

What do you wish you could tell every patient and why? I genuinely care about your overall health. I love what I do. Its very satisfying to take care of people and make them feel good.

If you could tell patients to do something (and they actually would), what would it be? Take care of yourself.

Why did you decide to become a dentist? I worked in a hospital as a medic so medicine and problem solving interested me.

Reviews & Testimonials

"Uodate 7/31/2026A Composite that I had in my front tooth for about 50 years broke off. I called on a Tuesday morning about coming in to see about it being repaired., I was called back immediately and it was repaired on Friday morning in about a half an hour. Dr. Kavanagh and his Able-bodied assistant worked wonders. Thank you.As a new patient, I expected a long wait for the first appointment, actually the wait was less than 24 hours. Came in for my first appointment, was seen on time, in a fabulous modern facility. The two ladies at the desk were enormously friendly, Jean, my hygienist, was personable, knowledgeable, and patient with all my questions. And very efficient. Dr Kavanaugh put me at ease immediately and as a fellow Navy veteran, we had some commonality, but he was also quite open and friendly, highly recommended.Second visit for follow up cleaning, and still just as awesome, thank you Jean!Third visit, to finish a deep cleaning, a wonderful experience 5/29/26David Manzi"
