“I saw "Dr. Avi" for the first time when my regular PCP had to cancel because of illness. The doctor's patience, wisdom, and kindness were apparent right away. He asked good questions and validated my concerns. I felt centered in my own care, which is no small thing in today's American industrialized medical complex. Very happy to return to him as needed.”

I relocated to NYC recently and am thrilled with Dr. Sonnenschein. He is willing to spend the needed time to talk through everything (yearly checkup) and did not feel rushed or like we don't have enough time to chat through everything.
