About Advanced Chiropractic

Founded by Dr. Ren Halverson, Advanced Chiropractic has served Brunswick, St. Simons Island, and surrounding South Georgia communities for over 40 years, helping more than 30,000 patients regain function, mobility, and quality of life.
A Legacy in Chiropractic
Dr. Halverson was first introduced to chiropractic as a patient after sustaining a serious fall while working in construction. Though he avoided broken bones, the injury significantly altered his posture and spinal mechanics. Chiropractic care played a pivotal role in his recovery—ultimately shaping his decision to pursue the profession.attended Life College in Marietta, Georgia, practiced in Atlanta for seven years, and relocated to Brunswick in 1987, where he established what would become a cornerstone chiropractic practice in the region.
Clinical Background & Specialized Experience
During his career, Dr. Halverson treated a wide range of patients, including:
Professional football players
Olympic athletes
Members of the U.S. Karate Team
Marathon runners and competitive swimmers
He was also the first chiropractor invited to join the General Motors workers’ compensation medical staff, serving both the Doraville (24,000 employees) and Jonesboro (16,000 employees) plants. This work provided extensive experience in spinal rehabilitation, repetitive strain injuries, and shoulder, elbow, and carpal tunnel conditions.
Dr. Halverson later expanded his clinical reach by opening additional practices in Jesup, Savannah, and St. Marys, Georgia, all of which continue to serve their communities today.
