Mission Statement-
I feel that in order for a patient to achieve maximum improvement with physical therapy, a good understanding of what is causing the problem is needed.

Treatment Philosophy
Our bodies function as a unit. If one part is hurt/injured/dysfunctional, the entire body suffers. My approach to physical therapy is the same with all my patients; I treat the whole body so that it can work together to enable function and performance. I firmly believe that patient involvement is key in recovery. I work closely with my patients to fully understand their needs and we work together to determine a course of treatment that encourages independence and promotes healing.
