Dr. Berber and Hannah had quick responses to any questions I had.

Reviewed on Jul 15, 2021

Dr. Berber is clinically solid, obviously very knowledgeable and well respected. That said, he spent a total of 11 minutes with me via Zoom and phone call combined, did not give me time to explain my symptoms or concerns and dismissed me with a couple of tests to be run as an "extra precaution". I do have a surgery referral from Dr. Tobias Carling in Tampa, but living in Michigan I am desperate for a closer option. Overall, Dr. Berber isn't a doctor I would recommend for consultation or illness discussion. I'm certain he is a phenomenal surgeon, but his explanation and discussion with patients is lacking.
