Meet Our Clinical Staff

  • 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.

    Karla received her Bachelor of Science in Nursing with High Distinction from the University of Nebraska Medical Center in 1996 and was inducted into the Sigma Theta Tau International Honor Society of Nursing.  In the early years of her nursing career, she worked in geriatrics and was intrigued by the aging & disease process and began to study about wellness & disease prevention. Karla struggled with headaches from the time she was a child, and as she learned more about health issues and holistic health care, she discovered that food allergies and toxins were the root causes, and she was able to restore her health with the help of an integrative clinical nutritionist.  Karla has been working in Integrative and Functional Medicine for over 15 years, assisting others to learn what we put into our bodies’ matters, and that with the right resources, our bodies can journey towards healing.  Karla is certified in heavy metal toxicology and chelation therapy from International IV Nutritional Therapy Global Physician Education and performs IV infusion therapy for the Carolina Center as well as our affiliated practice, Restore Health & Wellness.
