I saw this doctor for several years. I came consistently and on time. Recently I had to miss an appointment due to an emergency. He is charging me over $100.00 for missing the appointment. His normal charge is $30.00 (based on the deductible). When I tried to explain the reason for the missed appointment, he would not even let me finish speaking. He has also given my name and personal information to a collection agency, Pittsburgh Medical Bureau. This agency is threatening to ruin my credit. Dr. Berlin lied to this agency when he told them I made no effort to contact him.
