LINDSEY THOMAS, DC
Doctor of Chiropractic, Webster Technique Certified
Chiropractic wasn’t something Dr. Thomas grew up with. She knew she wanted to go into healthcare, but wasn’t exactly sure what that was. “I found myself at a crossroads in life and then met a person who was going to chiropractic school. We sat down and talked about it over lunch, and it made me look into what chiropractic was all about.”
The idea of natural healing really made sense to Dr. Thomas, especially since she was also getting into nutrition, exercise, and wellness at that time. “It was amazing to me that there was a profession that truly recognized the body’s ability to heal on its own.” She now uses this philosophy on a daily basis to provide the highest quality of care to all of her patients.
