I am a physical therapist in private practice in Grand Junction, CO. My wife, Susie (also a PT), and children, Suriya (13) and Katie (16) live in the ‘Redlands’, just out of the city limits. Our children are involved in sports, music (guitar & flute) and school. Our home is a mile from the clinic with my mother-in-law, two dogs, two cats, five chickens, five goats, three horses and a bunch of coyote & foxes. Hobbies…ha! I grew up in Flagstaff, AZ. I am a graduate of Northern Arizona University (NAU) (BSPT, 1981), Samuel Merritt College (SMC) (MSPT,1997) and Regis University (DPT, 2007). I now teach clinical courses in manual therapy and leadership & ethics at Regis U. and EIM. I’m board certified in orthopaedics (OCS, 1995) and a fellow of the American Academy of Orthopaedic Manual Physical Therapy (FAAOMPT, 1999).  I recently was appointed to the Physical Therapy Board for DORA in Colorado, 2-year term (2012-14).
