Physical Therapist

Scott’s interest in working with a chiropractor started in 2001 right in here in Roswell, Georgia. Curiosity with an open mind outside of the traditional medical paradigm, he decided to work with a chiropractor who wanted to have physical therapy services in conjunction with his medical and chiropractic services.

It wasn’t until then, the opportunity to make greater impact on patient outcomes became more clear and exciting. Through many trials, the development of simple spinal exercise programs with specific outcomes to match the goal of chiropractic adjustments paved way for a bright future with powerful treatment implications.

The main component of the spine exercise program is to control the soft tissue and muscle pain around that spine. It only made sense that when employing chiropractic adjustments affecting the mobility of the spinal segments giving pain relief, it is then physical therapy is used to assist in exercising muscles to hold that adjustment. As a result, thousands of patients have benefited from this combined approached since 2001.
