Dr. Lada Fishman

We are excited to announce that Dr. Lada Fishman has returned to our practice as our new associate dentist.  Dr. Fishman previously worked with us as a dental assistant. In 2012 she was accepted to NYU College of Dentistry, and moved to New York City. In the course of the next five years she graduated dental school and completed a one year general practice dentistry program in Woodhull Hospital in Brooklyn. Dr. Fishman received her BS in Science from Temple University.

Dr. Lada Fishman was born in the former Soviet Union, and as a small child her family decided to move to Israel. At the age of 18 she immigrated to the United States and settled in Philadelphia, PA. 

Lada discovered the world of dental assisting by accident but she quickly realized that dentistry was a lifelong passion.


Dr. Louis Vida

Congratulations. Dr. Louis Vida has retired from the practice. He is enjoying his golden retirement years by keeping active playing soccer and tennis. Most important he is trying to keep up with his grandchildren. Dr. Vida just returned from a mission trip to Guatemala where he was doing volunteer dentistry on children in remote areas who have no access to dentistry. Best of luck, Dr Vida. You are missed.
