Dr. Marc Stuart Ernstoff, MD

Upon my first meeting with Dr. Ernstoff I knew right away he was the doctor for me. I was seeing him to get a second opinion on what to do about my renal cancer. The first doctor I had seen told me I probably only had months to live and wanted me to enroll in a clinical trial. But I knew I had to get a second opinion and I am so glad I did. Dr. Ernstoff put me on a chemo pill that I took for 2 1/2 years. To make a long story short here I am over 12 years later, still alive, still have renal cancer that seems to just stay asleep. I've asked my primary doctor why am I still alive, and he says he really doesn't know. I think it is because of the wonderful care I got in the beginning from Dr. Ernstoff and from the grace of God. I would recommend Dr. Ernstoff to anyone. He always took his time with me and my family to explain everything and I am so grateful for that.

Dr Ernstoff is an amazing doctor, he took very good care of me while treating my cancer. He answered all my questions and took whatever time I needed. If you have to use him for your treatment you will be very lucky to have him.

I followed Dr. Ernstoff from Cleveland Clinic to Roswell Park Cancer Center in Buffalo because I needed the benefit of his experience and expertise in treating my advanced melanoma cancer. He is aware of the latest research, and is actively involved in some of it. He gives patients his full attention, and treats them as partners in the healing process.
