Meet the Doctor


Dorothy E. Whalen, D.D.S, P.C.

I have been fortunate to be in practice in New York for over 30 years. I truly enjoy my profession, especially knowing that I am able to help my patients achieve beautiful, healthy, confident smiles for a lifetime. I appreciate and respect the friendships I have built over the years with my patients and their families, and I am always happy to hear about my patients' successes even after they've completed their treatment with me.

From your first phone call, until your final appointment, I strive to deliver outstanding orthodontic care, and to create a positive orthodontic experience that will keep you smiling for many years to come. My staff and I are proud of our practice, and the reputation we have earned over the years, and we look forward to sharing in this wonderful life-changing experience with you.
