He earned his Bachelor of Science degree in General Biology at the University of Arizona in 1982 and his Doctor of Medicine degree at the University of Arizona College Of Medicine in 1986. He completed his Internal Medicine residency at Banner Good Samaritan Medical Center/Phoenix Veterans Administration Medical Center in 1989 and worked in the emergency departments of both hospitals from 1988 to 1989.

Prior to joining CTCA®, Dr. Gilson practiced primary care internal medicine in the Phoenix area for 25 years.

From 1998 to 2013, he ran his own private internal medicine practice in Tempe, adding medical weight-loss services to the practice in 2008. In 2013, he became a Staff Physician providing primary-care ambulatory services at a large medical center in Phoenix. Dr. Gilson is Board Certified in Internal Medicine by the American Board of Internal Medicine. He is licensed to practice medicine by the State of Arizona, and is a member of the American College of Physicians.

Since joining CTCA in 2014 as a physician in the Internal Medicine Clinic, Dr. Gilson has enjoyed working closely with the oncologists and other clinicians who manage our patients’ care while undergoing cancer treatment. “I have always attempted to treat my patients in the manner that I would like my family treated, so I fully embrace the Mother Standard® of care here,” says Dr. Gilson. “I feel very fortunate to have this opportunity to work alongside such a high-caliber team of caring, dedicated medical professionals, administrators and support staff.  I always feel confident that I have the resources, enthusiastic support and cooperation required to do what is best for our patients.”

Patient ratings
Star ratings and comments are only available for medical, radiation and gynecologic oncologists. Gynecologic surgical offerings are not included at this time due to a different survey tool required to evaluate these services. CTCA uses a validated Press Ganey® survey, which captures patient experience feedback for the primary oncology services of chemotherapy and radiation therapy at our comprehensive care and research centers. Following industry best practice, star ratings and comments are only published for physicians with a minimum of 30 completed patient surveys.
