Thank You For Caring

If it weren’t for Dr. Howard Epstein I would still be suffering with a major bladder and kidney infection that no one else could find after spending 4 miserable days in the hospital. Not only is treating my infection, but he was the one who discovered I have cancer on my right kidney. He ordered it to be frozen and now so far as I know the cancer is dead. He and his entire staff are among the most caring compassionate group of professionals I dealt with in some time. Thank You for caring.

I have only good things to say about Dr. Epstein

I have only good things to say about Dr. Epstein and his staff. Dr. Epstein was caring, clear, and very informative about the options I faced with the diagnosis of prostate cancer. His recommendation was radiation therapy and I am now undergoing treatment. I will recommend Dr. Epstein to anyone that asks me.

A Great Doctor

If you have a major problem after hours you can call his office and he will call you back. I have talked to him a 2am in the morning and when he is out of town. Very few doctors will do that. A great Doctor
