Dr. Roberta Van Zant

Dr. Van Zant practices Functional and Holistic Medicine. Functional medicine is individual based medical care, and focuses on true prevention as well as identifying the underlying causes of symptoms and disease with a goal of treating the cause and reestablishing optimal health. It is scientifically and physiologically based healthcare. Holistic Medicine is aimed at treating the entire person – mind, body and spirit – while recognizing that we are not split up into different “sections”, but rather interact as a whole, interconnected system.

Dr. Van Zant is also trained as an osteopathic physician. Osteopathic physicians receive 4 years of medical school training, and average an additional 120 hours of training in musculoskeletal medicine during medical school. Osteopathic physicians receive specialty training in family medicine and many different specialty medical fields, similar to M.D.s.  However, it is their ability to evaluate and treat musculoskeletal conditions that set them apart. Dr. Van Zant is board certified by the American Osteopathic Association in Family Medicine and Manipulative Medicine and sees patients for osteopathic treatment.

Dr. Van Zant is board certified in Family Medicine by the American Board of Family Medicine and the American Board of Osteopathic Family Physicians. She has received over 300 hours of additional training in functional and integrative medicine as well as osteopathic manipulation.

She received her medical degree from University of Texas Health Science Center Texas College of Osteopathic Medicine, completed her residency training in Family Medicine at Harrisburg Family Practice Residency Program in Harrisburg, PA, and then was the first graduate of the Women’s Health Fellowship through the University of Illinois College of Medicine in Peoria and Methodist Medical Center.
