Graduating in one of the inaugural classes at the Florida campus of Palmer Chiropractic College Dr. Joseph Wolfersberger, D.C. has been in practice for over a dozen years. Chiropractic has been part of his life since childhood in a small beach town on the Jersey Shore. In his senior year in high school a rough tackling drill at football practice caused a severe “whiplash injury” that required a longer course of treatment. It was a wonderful experience recovering from the injury, see others get better. This great experience set him on the path to becoming a Doctor of Chiropractic.

After high school, he decided to relocate to Jacksonville to attend the University of North Florida. After earning a bachelor's degree in Spanish from the University of North Florida, he worked in the banking and communication industries until a layoff from a job led him to reassess his career choice. He went back on his original path to becoming a chiropractor.

After becoming a Chiropractor, he was hired on with one of the most respected, experienced, and longest continuously operating clinics in the state of Florida. He then covered at several different chiropractic offices around North and Central Florida until finding his perfect fit with Florida Spine and Injury in Lake City.

Dr. Wolfersberger has 3 daughters, two of whom are adults and one pre-teen still at home. In his spare time he likes to do yoga, outdoor activities such as camping, hiking, riding bikes and kayaking/canoeing.
