Horrible and unprofessional!!!! My appointment today was at 1:45 and was told to wait I’m the car and they would call when ready. I completely understand due to COVID but you don’t call 2 1/2 hrs later than your Appointment!!! I’d like to charge Dr Dreyfuss for my time. After receiving my call asking if I was still there I said no and I will be calling to get my records transferred. Don’t wast your time. Find a different dr !!!!

I have been a patient of Dr. Dreyfuss' for nearly 30 years. I recently went through a health crisis and her care was of the utmost quality. Her expertise and determination to solve my problem made me feel at ease and comforted.

Dr. Dreyfuss has been my physician for over 30 years. She saw me through 3 births and recently a cancer scare. She is beyond compare and takes the time to explain, answer questions, and most importantly, LISTEN. Yes, the wait times in the waiting room are long, but when it is your turn, you are most happy she does not hurry through your appointment, instead taking the time as a doctor should.

Dr Dreyfuss is a wonderful caring and experienced doctor. She has seen me through two pregnancies and stayed the night in the hospital. I have also had her for a loss and the amount of time and support she gives is priceless. Worth any wait to me and her staff is great.
