I''m grateful for the excellent care that Dr James Martin has provided me over the last year. He''s not only a great oncologist, but his passionate and caring personality went above and beyond my expectations. I was brought to tears learning that he is leaving the Cleveland Clinic. My husband and I can only pray that the oncologist he is transferring me to is just as compassionate. Thank you Dr Martin for everything!
