Zane Smith

Zane Smith, PT, MPT, OCS


Zane is a native of the northwest and grew up in east Portland. He graduated from Eastern Washington University in 2003 with a Masters in Physical Therapy. He also has a BS in Human Biology. Zane believes that regardless of where the patient receives PT it must be comprehensive; encompassing not only tools to treat inflammation and pain, soft tissue dysfunction, muscle imbalances and specific weakness as well as overall functional limitations, but also enhancing the patients ability to treat themselves and continue to thrive on an independent basis. In addition to treating orthopedic conditions his other professional interests include the management of chronic headaches to include migraines as well as other chronic pain conditions. When not in the clinic Zane loves to spend time with his wife Leslie and their two children Zoe and Gage, at home in Washington. They enjoy snow skiing, fishing, camping and other outdoor activities. Zane and Leslie are heavily involved in their community and promoting a healthy lifestyle.
