About Us/Staff

Passion. Expertise. Quality.

Many of the area's best physicians refer their patients to Kassimir Physical Therapy with confidence that they will achieve their highest functional potential in a comfortable and skilled environment. 

Throughout the treatment experience, each patient will receive personalized care from our physical therapists, as well as dedicated assistance in all aspects of the recovery process from our caring staff.  Our large volume of patient referrals and satisfied returning patients are a testament to the quality of care the "Ultimate Rehab" experience provides.

At Kassimir Physical Therapy, we fully appreciate that the quality of our patients' lives depends on our dedication and expertise, and it is our commitment to provide each patient with the exceptional care they need to maximize their rehabilitation potential. 


Comprehensive Evaluation

Each patient’s first visit to Kassimir Physical Therapy will involve an in-depth initial evaluation performed by one of our physical therapists. The evaluation begins with a detailed history and physical exam, which includes specialized tests and measurements relevant to each patient’s condition. Based on the evaluation, the therapist will develop an individualized treatment plan and establish therapeutic goals based on the patient's needs and the referring provider’s recommendations.

 Kassimir Physical Therapy offers a variety of clinically proven treatments coupled with the latest technology and equipment to help each patient achieve their rehab goals.  Our clinic boasts a state-of-the-art gym and the most advanced, effective custom splinting available.
