Our Mission

Our mission at Motus Physical Therapy and Performance is to help people move better and feel better. We want improve both individual and community quality of life, sport, and health by offering the advanced, progressive, evidence-based, innovative rehabilitative and training services.


We believe that how you move affects how you function or dysfunction throughout your life. This could be playing a sport, going to the gym, or just walking in the store.  We take the time to not only give the highest quality of care, but move beyond typical physical therapy to integrate principles from the movement, rehab, and strength and conditioning industries to help you achieve your goals. We look to find and treat the source of pain and injury for results that will last.


We also want to expand movement-based principles into the fitness/athletic communities to help individuals and athletes not only increase performance, but reduce risk of injury.  With so many fads, our goal is to bring truth, quality, and research-based services to the health and fitness worlds. Learning how, when, and how much to move can be the difference between a healthy body and injury. We strive to constantly evolve with the science to help people live stronger, more resilient, and with less pain.
