Patient Comments (6)
This is THE WORST doctor I have EVER been to in my ENTIRE life!!!! He is a COMPLETE CON ARTIST!! He first tried to make me his medical guinea pig by prescribing drugs to me after admitting he had no idea what the source or solution was to my problem. I was also billed over $100 for a blood test that I explicitly said I did not want if it would be an extra charge. He hasn't answered my phone calls since to get the test results and now I am billed for a test I did not receive! It's been A MONTH!!!

It took 4 months to get an appointment for my 92 years old disabled Purple Heart veteran. Father. He was basically written off by Dr Nahm. My mother said it was the most useless Drs appointment he'd ever had. Felt that the doctors thought he's 92 years old he should be living with pain at this point. No effort in trying to find the cause of the pain which is why he went to this doctor in the first place.
Port Chester, NY |
I gave him two stars because he's pleasant and will explain what's not wrong with you. Ultimately, with cues and prompts, I found myself doing better Google queries and ultimately determined what my problem was and concluded I was probably a better Doctor than him. The problem is that I'm a carpet cleaner.

No one was even at the office. They sent a confirmation email but then they weren't there. Last time we waited for an hour.
New York, NY |
Although the doctor seemed interested and spent adequate time with me, his office staff is either incapable of answering phones and relaying messages or he is the one who does not get back to patients. Nevertheless, most people want to know that they can reach a doctor and my experience in several instances, was no response from the doctor. In fact, often, when you call during business hours, you will get an automated message.
in Cos Cob, CT |
No on-call coverage and does not return phone calls. His office didn't know I had called the evening before, even though I left 2 messages with his answering service. Prescribed outdated migraine medication with inadequate instructions. Charges administrative fee for dealing with insuance companies on pre-authorizations.
