Dr. Grant Scarborough, MD- Founder & Executive Director
A native of Columbus, Dr. Grant Scarborough graduated from the University of Georgia with a degree in Biology. Immediately following graduation, he spent two years on staff with Young Life in metro-Atlanta. It was during this time that Grant became involved in an outreach effort to the homeless of downtown Atlanta, and soon felt called to actively work with and for the underserved around him. After seeking the counsel of several trusted advisors, Grant came to believe that this calling would lead him to practice medicine. Dr. Scarborough earned his medical degree from Mercer Medical School in 2003, completed his internal medicine and pediatric residency at the University of Tennessee – Memphis, and finished his Med/Peds residency at the University of Tennessee in June 2007. In the fall of 2007, Dr. Scarborough returned to Georgia as co-founder of Christ Community Health Services of Augusta. The next four years would see the addition of providers and staff alike, with tens of thousands of patient lives impacted for the glory of God through CCHS. After several years in Augusta, Dr. Scarborough and his family felt the call of the Lord again, this time to Columbus, where they moved in July of 2011. As a board certified pediatrician and internal medicine physician, Grant desires to see God glorified through caring for the poor and discipling young medical students to do the same.
