Dr. Chanel Barnes, DC, L.Ac.

Licensed Acupuncturist
Becoming a healer has been a lifelong interest for Dr. Barnes.

Receiving the benefits of acupuncture along with chiropractic had inspired her to pursue learning both healing arts. She then continued her education to become an acupuncturist and chiropractor at  Southern California University of Health Sciences. There, Dr. Barnes earned a Masters in Acupuncture and Oriental Medicine and a Doctorate in Chiropractic.
