Catalyst Sports Medicine began on January 1st of 2013 when then General Manager John Knutson and Clinic Director J.W. Matheson purchased the business entity from Rich Larsen, who previously owned Larsen Sports Medicine & Physical Therapy.
The 7,200-square-foot clinic, located at 2305 Willis Miller Drive in Hudson’s Industrial Park, was quickly becoming too small and congested as services were added and the business grew. Knutson and Matheson always had a goal of transforming the physical therapy clinic into a sports medicine practice. While specializing in physical therapy, athletic training, industrial medicine, orthopaedic massage services and performance training for athletes were added. As all areas of the practice were growing, the need for more space was imminent. Matheson and Knutson purchased the old “Skatery” building on the corner of Hanley & O’Keefe Roads in January of 2015 and began an extensive renovation for the sports medicine practice. On September 1st of 2015, Catalyst opened the doors to the newly renovated 22,000-square-foot facility located on 2.5 acres of land. It included an expanded PT clinic and performance training center and also a new 10,300-square-foot indoor turf training center which sets Catalyst apart from all other therapy clinics and gyms in the region.
Today, Catalyst employs 20 people including physical therapists, PTAs, athletic trainers, massage therapists, strength coaches and administrative and customer service personnel.
Mission & Vision
To always exceed the expectations of our clients.
To be considered the premier provider of services by our clients and industry peers in the areas of Physical Therapy, Athletic Training, Strength and Conditioning, Industrial Medicine and Wellness Programs.
