Central Maine Healthcare is pleased to welcome Charles Stewart, MD.

Dr. Stewart attended the University of Southwestern Medical School where he received his doctorate, before completing an internship in the Department of General Surgery at Baylor University Medical Center and a residency at the Department of Radiation Oncology at the Hospital of the University of Pennsylvania. Dr. Stewart also has a Doctor of Philosophy degree in Neuroscience from the University of Texas Southwestern Graduate School.

Prior to joining Central Maine Healthcare, Dr. Stewart was a radiation oncologist at Saint Francis Hospital in Tulsa, Oklahoma, where he was also the medical director of the Department of Radiation Oncology.

Throughout his career, his cancer treatment focus has been on head and neck, lung, breast prostate, central nervous system and lymphoma.

Dr. Stewart says he enjoys building long-term relationships with patients. “I see myself as a problem-solver and an educator,” Dr. Stewart said. “I actively listen to patients tell their story and work together with them to choose their course of treatment.”
