What Other Are Saying

Lovely Doctor. Made me feel very comfortable. She was very thorough. Highly recommend.

Dr. Epstein took the time to understand what my problem was and even asked me if she answered all of my questions. She outlined what the causes of my hives could be, explained what the work up would be, but did it in a non-alarming way. I was extremely anxious and she reassured me. She also called me back as soon as the blood tests came back and even though she wanted me to be further evaluated for my thyroid, she was reassuring. Friendly and professional. Staff very welcoming. I’m impressed. Wonderful experience and nice change from experiences I have had before.

I was treated by my primary care doctor for a viral infection, which has been getting worse. I was extremely upset, as I have a vacation planned. My cough was severe and I had a fever, so I used Zocdoc and got an appointment right away. The wait time was about 10 minutes and Dr. Epstein determined that I need an antibiotic and a different inhaler. She actually took me off of the over the counter medication that I was taking, and that really helped. I can't believe how much better I feel this morning. The office staff was extremely well informed and pleasant. I definitely will be using Dr. Epstein again.
