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 relationships 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 Alexander M

Any fears or worries I felt before the dental implant procedure were immediately dismissed as I was made physically and mentally at ease. I was always in the best professional hands I had a painless experience both during and on the days afterwards.I cannot believe that I waited so long to have the surgery when it was such a seamless operation
