Dennis Halpin, DPT, LSVT

Dennis pursued his Doctorate of Physical Therapy degree at Misericordia University in Dallas, PA. After college he returned to his hometown in the Utica, NY area where he gained valuable experience treating people with various orthopedic and neurological conditions (Parkinson's Disease). He then moved to Seattle, WA where he enjoyed working with people in both conservative ( = non-operative) and post-operative treatment in an orthopedic-sports setting.

Dennis has a history of sports-related injuries that sidelined him time and again. At PT he was fortunate enough to see the close relationships fostered between patients and their therapists, and believes this is an integral part of the patient experience.

Dennis enjoys working in the orthopedic setting with various patients, alongside working on people's balance to improve safety and reduce their risk of falls.

His hobbies include playing / watching soccer (big Manchester United fan), hiking, biking, trail running, reading, playing with his cat, and going for walks with his girlfriend.
