About us:

Fusion Physical Therapy and Cardiac Rehabilitation is unique in that it offers many varieties of Physical Therapy and includes Athletic Training. We have Physical Therapists who specialize in different treatment techniques that are hard to find in the outpatient physical therapy world. This includes dry needling, post concussion and vestibular rehabilitation, cardiac rehabilitation, and golf performance through Titleist Certifications. This clinic is also unique in that it has Athletic Trainers that work with our Physical Therapists. Each patient will see a Physical Therapist for the evaluation and all manual therapy techniques. Once the Physical Therapist has completed manual therapy you will then continue your one on one treatment with an Athletic Trainer who will help you gain strength, mobility, and teach you functional movements that are geared towards your goals. This business model is rare because it offers one on one treatment throughout the entire appointment and is all focused on what you want to achieve.
