John C. Pittman, M.D., Medical Director
Dr. Pittman received his medical degree from Mercer University in Macon, Georgia in 1986 and attended the Pediatric Residency Program at NC Baptist Hospital in Winston-Salem, North Carolina with an emphasis in Preventive Medicine. Later, while serving as Emergency Department Director at hospitals in Rocky Mount and Southport, NC, he began exploring ways to combine conventional medicine with nutrition, botanicals, and other natural therapies as an integral part of clinical medical practice.
Since founding the Carolina Center in 1994, Dr. Pittman has further enhanced his understanding of integrative medicine through clinical training at the Autism Research Institute and the International Lyme and Associated Diseases Society’s Physician Training Program.
He has lectured frequently at the UNC School of Medicine’s Program on Integrative Medicine and presently serves as a member of the state’s Vector Disease Task Force and was the former President of the North Carolina Integrative Medicine Society. From the beginning, Dr. Pittman’s vision for the Center was to bring together multiple healing modalities in order to help patients overcome chronic degenerative illnesses and bolster their health and wellness.
