Greg Klein

Greg Klein
- PTA
Physical Therapist Assistant

Greg graduated from the Physical Therapy Assistant Program at Mt. Hood Community College in 2009. Since then he has practiced in both inpatient hospital care and outpatient orthopedics while living in Corvallis. In September of 2014, he moved back to Portland and joined the team at Cascade 205. 

A former field biologist and environmental consultant, Greg came to Physical Therapy later in life pursuing an interest in the mechanics of the human body and a desire to work with people. Outside of work, he spends a fair amount of time exploring the outdoors via mountain biking, hiking, backpacking, and skiing. In 1989, he took his first yoga class for college credit and has kept up the practice over the years, which has included teaching introductory yoga classes for at-risk youth.  He also likes to stay in tune with his lifelong love of music by playing bass in a music ensemble that explores various music styles from South America. “Playing an instrument has actually been instructive for my career in Physical Therapy. Musicians have an uphill battle against the adverse effects from repetitive strain and prolonged postures. So it’s great to be in a field that can help.”
