My doctor since 2000. He has never ever let me down!! I am not an Oncology patient. I am a person with a hemoglobinopathy called S/C disease. I do not have Sickle Cell Anemia. However I don't have any normal hemoglobin as the Sickle Cell Anemia patient designated S/S. Dr. Guthrie never showed any problem with this diagnosis. He just punched in and went to work! Dr. Guthrie takes care of my S/C disorder famously. I just wish he was my Primary Care Dr.!! He is the best!!!
