About Us

A Brief History:

Dr. Charles A. Fischbein opened the doors at 1078 West Main Street in Waterbury, CT. to begin private practice in July of 1982. With a staff of five, the office was open 5 days a week and Dr. Fischbein was available 24/7 for our increasing patient population. In 1983 Dr. Jeffrey Berg joined the practice followed by Dr. Maria Tasso in 1987 and Dr. Neil Vitale in 1989. With the addition of the three doctors, we were able to include Saturday office hours for our patient’s convenience as well as open a satellite office in Southbury, CT.

In 1994 we moved into a larger office suite located at 160 Robbins Street in Waterbury, CT. At this time, Dr. Ellen Mascoli-Lanza, certified in both Internal and Pediatric medicine, came aboard.  Dr. Ena Chow started in July of 1997 and was later joined by Maria Bernardi, PAC. In 2007 we welcomed Neysa McDonald, MD and in 2008 Sarah Baum, MD returned to the Waterbury area to join our growing practice. With the retirement of Dr. Neil Vitale from primary care pediatrics in late 2013, Dr. Cynthia Roque, a Waterbury native, came to Pediatric Associates from CHC in New London. In early 2016 we added one more “Jersey Boy,” Dr. Stephen Maddox with a background of more than ten years in practice.

Our caring office staff has been handpicked to provide the all important link between doctor and patient in the office and on the phone. As children's doctors, we are committed to ensuring the healthy progress, behavior and development of all children in our care.
