Very prompt, comprehensive, and to the point. He answers his personal cell phone, which shows how much he really cares about his patients - I've never had a doctor do that before.

October 5, 2019Mary G.Verified patient
Horrendous practice!!! I was waiting for two hours, with all kinds of weird patients. There was one patient who was screaming and creating a ruckus in the waiting room, complaining about the doctor. I did not feel safe or comfortable in that environment. There were people talking loudly on their cell phones. It was managed extremely poorly and I will not be seeing this doctor again.

A little unconventional/quirky but spent a lot of time with me to answer my questions. Went into depth on the underlying issues.

Great doctor. He really listens and explains his thinking to help you understand where your problems are coming from. Down to earth, friendly, and caring professional.

Dr Ferstenberg is amazing ! Truly cannot thank him enough for his talent and kindness. Unfortunately his staff made it quite clear that only 1 out of 3 of them are properly trained. They are all very friendly and kind, but did not know what they were doing.
April 15, 2019Initials hidden
He was very welcoming, polite and intelligent. Felt comfortable asking whatever questions needed. After waiting 2 hours (for a consult) and threatening to walk out I was finally able to be seen for five minutes... Going to give his office one more chance.
April 7, 2019Initials hidden
Busy office but I've found Dr. Ferstenberg to be extremely knowledgeable and willing to patiently talk through any and all concerns. I've gotten answers from him I couldn't get from other doctors.
