James RoweJames Rowe, DC

Outreach Coordinator

Dr. James Rowe has served the chiropractic needs of various communities throughout the metropolitan Atlanta area since June 2000. Through years of chiropractic experience gained from working with multiple demographics, Dr. Rowe recognized a direct correlation between a patient’s physical and emotional health in regards to their overall healing process. He observed that a patient’s physical health was often impeded and in some cases prevented due to the patient’s mental condition. As a result, Dr. Rowe has resolved that optimal health is achievable only by addressing a patient’s physical and emotional health simultaneously.

Dr. Rowe also served as a juvenile substance abuse counselor and volunteered with a community service organization in which he saw the devastating effects of substance abuse in men and women of all ages and ethnicities. This experience has given him a significant understanding of various issues affecting those who struggle with addictive behaviors and has allowed him unique insight into the effective treatment needed to assist sufferers in their overall recovery process.

Dr. Rowe’s skill and experience have culminated into him becoming a life coach. He plans to operate in this role as well as Director of Marketing/Business Development as part of the team at The Carter Treatment Center where he will aid clients in reaching their potential and assist them in identifying barriers that prevent them from doing so.​​​​​​
