Dr Greg Barnes D.C., B.S., PSc. D

Clinic Director

Dr. Greg Barnes experienced the amazing benefits of chiropractic in middle school. He was intrigued by how it benefited him with neck pain and allergies when traditional medical treatments failed. He received undergraduate training at the University of Minnesota and Excelsior University. In 2006 he enrolled at Life University Chiropractic College and graduated in 2009, just 3.5 years after enrolling (typically takes 4-5 years). In 2011, he opened Greenway Health Center in Raleigh, NC and it quickly became one of the busiest natural health care clinics on the East Coast.

He has received extensive postgraduate training in nutrition, lifestyle coaching, pediatrics, functional medicine and an advanced form of corrective chiropractic care. This allows him to provide the highest level of care for his patients, from all walks of life.

In 2019 he received his Doctorate in Pastoral Science (PSc D.) and he is also currently finishing his Functional Medicine Certification and degree!

Outside of the office Dr. Barnes enjoys spending time with his wife Jani, daughter Nora, son Leo, and his dogs Coco and Juno. He’s also a soccer fanatic and is always looking for a good book recommendation!
