Barb Allan, PT

More than thirty years of experience in the field of physical therapy and rehabilitation have provided me with an eye toward evaluative skills to assess the whole body to determine and alleviate the chief complaint, focusing on biomechanics to avoid injury while improving performance. An understanding of building upon component parts for rapid improvement and ongoing successful performance is a skill that I apply to each of my endeavors.

A ‘constant learner’, I continue to expand my knowledge by learning anything related to health and wellness. I enjoy treating a variety of orthopedic patients of all ages and abilities. I have specialized knowledge in treating vestibular and post concussive patients. I have a love of cycling and if I can help a cyclist get back on the bike, be it a bike fit or healing their body, I will call it a great day. I feel that yoga can be very healing to the body if performed with proper alignment and enjoy helping patients return to their mat successfully. In my off-work time, I enjoy cycling, both road and mountain and skiing. My dog Weston and I, are a certified therapy team with Pet Partners and visit residents at local assistive living center.
