This guy single handedly saved my wife’s life. He doesn’t mess around. He knows how to do one thing well, cure cancer. He’s straight shooting, but has a sense of humor as well. His nursing and chemo staff are very knowledgeable about their work. My wife and I are glad that we chose Dr Tisman for chemo. Well worth the extra money that you will pay to have him be your doctor. If you had a choice to live and pay some extra money, or take your chances with whatever doctor your insurance gave you, which would you choose? That’s right… five stars.
