Testimonials from Dr. Feinstein's Patients

He is an excellent physician and very knowledgeable about the various chemotherapy drugs available and takes the time with his patients to make sure they understand the treatment regimen. I am very glad he is my mother's oncologist over the last four years in her fight with cancer.

Dr. Feinstein and his staff are just great with me. Dr. Feinstein went the extra mile with me to see my rare cancer had returned. I was treated at the Atlanta VA 9 years ago and started having some problems 7 years later after treatments; but couldn't find out what's causing the symptoms. But, finding Dr. Feinstein and he went the extra mile to do a biopsy in an area that no one wanted to do; was just extraordinary. No Lymphoma show it ugly face and I have a little bit of peace of mind. Dr. Feinstein referred me to a Rheumatologist that I'm hoping can find out what's going on. I have two now and they don't have a clue, but I'm praying this one will help me. I am sooo thankful for finding Dr. Feinstein, and he has good bedside manner...Love it.
