"How far you go in life depends on your being tender with the young, compassionate with the aged, sympathetic with the striving, and tolerant of the weak and strong. Because someday in life you will have been all of these." -- George Washington Carver.

My father was my first mentor. He is an outstanding pediatric subspecialist and always loved children and going to the hospital daily to take care of them.

Prior to attending medical school, I earned a Masters in Public Health Nutrition.

I have been with the Mid-Atlantic Permanente Medical Group since 1988. I chose to practice medicine here because I wanted to focus on taking care of patients and not worry about running a business. Pediatric nutrition and adolescent challenges are my areas of special interest.

What My Patients Say

Dr. Hellerstein is an excellent pediatrician. She takes the time to address all of my concerns without me feeling rushed or like an overbearing new mom. A nurse at Holy Cross recommended her, and I'm so glad she did. - JAC

She is wonderful. She is like one of our family: Friendly, caring, nice. We have been with her for the last four years. She is perfect. - SK

Dr. Hellerstein has been an excellent doctor! My children feel comfortable with her, and I feel confident in her advice and care as a parent. We love Dr. Hellerstein! - JS

Dr. Hellerstein is fantastic: Great quality of care, runs on time, available via email when an in-person visit not essential. - ES

Dr. Hellerstein has been our pediatrician since 2010. Moving across country, finding a pediatrician for our then 3-year-old was a top priority. We found Dr. Hellerstein was one of the top-rated pediatricians in the area and have loved having her as our children's doctor. She is thorough, professional and a natural with children. Our son was born in 2012 and of course Dr. Hellerstein was his first doctor. She has watched our kids grow and I trust her completely. It is so nice to have a doctor who truly cares about our kids, remembers them when she sees them, and even asks about things she knows they are interested in. We couldn't be happier. - VR
