Colin Hoobler, PT, DPT, MS

Inventor, Founder

Colin earned a Doctor of Physical Therapy from Boston University, master’s degree in Physical Therapy from Drexel University, master’s degree in Exercise and Movement Science from University of Oregon and bachelor’s degree in Kinesiology from Oregon State University.  Colin’s passion is to improve the lives of vulnerable populations, such as older adults, children and people suffering from chronic pain. To this end, he founded c.h. Physical Therapy in 2002 and has been a health writer for the Oregonian since 2012.  In 2008, he created the “The Fitness Show”, a TV series on PBS that educated viewers on the use of exercise to overcome injury and disease. Colin was a health expert for KGW Channel 8 News from 2009 to 2012 and has authored 2 books: “The Advanced Training Specialist”, a textbook for medical providers and “Lose the Wait” for those interested in safe, time-sensitive exercise techniques.

Chief Operating Officer

Ann earned a Doctor of Physical Therapy from Pacific University.  She is a former computer engineer and received an electrical engineering degree from the University of California Davis.  Ann has extensive clinical experience with older adults, including those suffering from severe balance deficiencies as a result of strokemultiple sclerosis and Parkinson’s Disease. Her passion is to improve the quality of life of older adults by using research and principles of exercise physiology.

A long time ago, in a laboratory far, far away…

…Colin Hoobler, a Doctor of Physical Therapy & Biomechanist, conceived the idea of S3 Balance® in the University of Oregon Balance Laboratory while completing his first master’s degree. Then came two decades of testing and research to fine-tune a safe way for vulnerable older adults to independently perform standing balance/strengthening exercise to reduce fall risk. Twenty years later, S3 Balance® was born.
