Back Pain
From lower back tension to disc issues, Dr. Britt uses a movement-based approach to find and fix the root cause — not just the symptom.
Neck Pain & Headaches
Tension headaches and cervical pain respond extremely well to chiropractic. Many patients feel relief after just the first visit.

Sharp, shooting leg pain from sciatic nerve compression — chiropractic and movement therapy can provide lasting relief without surgery.
Sports Injuries
From weekend warriors to high school athletes — Dr. Britt uses FMS screening and SFMA to keep you performing and prevent re-injury.
