Meet the Team

Dr. John Van Dam, D.C.

Owner & Chiropractor

Originally from St. Petersburg, Florida, Dr. Van Dam served 10 years on active duty in the United States Air Force as a medic, including time in Texas and an assignment in San Antonio. After experiencing the Texas Hill Country, he knew it was a place and community he wanted to return to and serve. He continues his military service today as a member of the United States Air Force Reserve.

His military medical experience includes work in emergency medicine, intensive care, general surgery, and family medicine during assignments in Texas and Germany. While stationed at Ramstein Air Base in Germany, he helped establish the base's ambulance service and spent two years helping lead the program before leaving active duty. That experience strengthened his connection to the first responder community and his appreciation for those who dedicate their lives to serving others. His military medical background provided a strong clinical foundation that continues to shape his hands-on, patient-focused approach to care.

Dr. Van Dam earned his Doctor of Chiropractic degree from National University of Health Sciences. He further advanced his training during a clinical rotation with the Bay Pines Veterans Affairs Healthcare System, where he worked closely with veterans to restore mobility, reduce pain, and improve overall function.

In practice, he focuses on personalized care tailored to each patient. He utilizes a range of techniques, including diversified adjustments, flexion-distraction, drop-table methods, myofascial release, and instrument-assisted soft tissue mobilization (IASTM). He is also Webster Technique certified through the International Chiropractic Pediatric Association.

Dr. Van Dam enjoys caring for families, active individuals, and those looking to stay mobile and engaged in the activities they love, with a focus on improving function, independence, and quality of life.

Outside the office, he values spending time with his wife and their three children and embracing the family-centered lifestyle of the Texas Hill Country. Whether enjoying time together outdoors, supporting their children's activities, or giving back through local programs and community involvement, he and his family believe in finding a meaningful balance between work, family, and serving the community they are proud to call home.
