Kai Pedersen PT
Kai has worked closely with Orthopedic surgeons, Neurosurgeons, and other professionals in the area for more than 17 years.  He is active with continuing education in Orthopedics and Manual Therapy.  Kai is a member of the American Association of Physical Therapy (Orthopedic and Private Practice Sections), the American Academy of Orthopedic Manual Therapy, and the Pennsylvania Physical Therapy Association.  His educational background includes an Associates in Zoology, Bachelors in Psychology, Masters in Gerontology, and a Masters in Physical Therapy.  His graduate research was in the area of ergonomics. 

Kai believes in educating every patient about their diagnosis; from anatomy to treatment protocols.  There is a constant flow of new research in Physical Therapy.

Patient participation is important to Kai in order to achieve optimal results in as short as time period as possible.  He is familiar with surgical procedures and treatment protocols for each procedure.  Patients are given the tools needed to work on their program at home; he can even send home exercises through the internet.

When not in the clinic, Kai enjoys working with his wife Jean on their small farm nearby and getting away on fishing trips.  He appreciates his improved lifestyle gained from a hip replacement.
