Marie Szczyglowski, PTA

Owner/ Physical Therapist Assistant

Cardinal Physical Therapy and Rehabilitation is locally owned and operated by Marie Szczyglowski.  Marie has been in the therapy field since 1996.  She graduated from Kent State University in 1999 with a Physical Therapy Assistant degree. 


After spending 12 years in the outpatient physical therapy arena with a strong emphasis in operational management, Marie made the decision to marry her clinical and operational knowledge to develop a new leader in outpatient therapy: Cardinal Physical Therapy and Rehabilitation.

In January 2012, Cardinal Physical Therapy opened its first patient care facility in Chesterland, Ohio.  Marie chose the Chesterland area so she could make a difference in this and surrounding communities where her own family resides.

Dr. Jennie Avsec, PT, DPT

Physical Therapist

Dr. Avsec completed her Doctor of Physical Therapy degree and her Bachelor of Science degree in Biology at Walsh University. Dr. Avsec's clinical rotations had a heavy emphasis in manual therapy which she has transitioned into the clinic.


Dr. Avsec enjoys working with a variety of orthopedic patients of all ranges, as well as specializing in a variety of pediatric conditions. She believes that patient education, maintaining a healthy patient/therapist relationship, and treating the patient as a whole is essential to the quality of care.


Dr. Avsec’s goal for every patient is independence, learning how to maintain optimal function, and to decrease the risk of future pain and injury.
