Injury Prevention & Rehab

Helping patients both prevent future injuries and recover from past ones

The goal of physical therapy is to set the patient up for success. We want to use our skills to treat the current issue that you are dealing with, but also work to give you the tools to make sure it can be managed long term. Patient education and physical therapy treatment is a big part of our care.

Individualized Approach


Every patient is different and so is our approach to treating them.

Every injury is not the same for every patient, thus every treatment can’t be. For physical therapy to be effective each treatment approach must be tailored for the individual and must include more than a physical approach. With every patient we take the time to analyze every aspect of the injury and work to address all issues to ensure the best recovery possible.
