Nice doctor but Does not listen to patient concerns whether that be long term medication side effects or addressing debilitating symptoms .
I visited a doctor Allan Klein MD regarding a heart problem. In another hospital they were not able to accurately determine my problem of severe pain around the heart. After seeing the scan, the test results and especially when he asked me about my pain where I described where and how intense the pain was. The doctor made an accurate diagnosis of perimyocarditis, showed me the problem on the scans, discussed with me the treatment and further steps to recovery. Absolutely perfect, detailed approach. The doctor is very educated and knows what he is talking about. I am happy and grateful for his help
