Doctor of Physical Therapy

Dr. Marybeth Grant-Beuttler is a full, tenured professor and the program director for the Oregon Tech/Oregon Health Sciences University Doctor of Physical Therapy Program. She has been teaching in entry-level physical therapy programs since September 1998 and a core faculty member at Oregon Tech since 2022. As a practicing physical therapist, Dr. Grant-Beuttler has been a Certified Pediatric Specialist since 2006. She has worked in most areas of pediatric practice, including, a large children’s hospital as an acute care clinician, a Neonatal Intensive Care Unit, and acute pediatric wound care, a school district, early intervention, acute pediatric rehabilitation, and pediatric outpatient center. Dr. Grant-Beuttler advocates for experiential learning in her courses and has a long history running integrated clinical experiences including:
• Shapes- a middle school PE class for children who met the criteria for and self-identified as Overweight or obese,
• Balanced Families- a weekly dance class for children with neurological movement disorders and a concurrent support group for their families,
• Toe Walking group- a weekly activity program for children who toe walk,
• Social Gaming Club- With a local clinic, Tater Tots, Dr. Kayla Taylor and Dr. Grant-Beuttler, coordinate an ICE
• Mini-Kickers- a YMCA supported community group focused on teaching 2–4-year-olds to play soccer.
Her research focuses on promoting the development of gait and postural control in standing and function with children. She works to develop technology systems that supports rehearsal of motor skills in the natural environment.
Beyond the university and clinic, Dr. Grant-Beuttler shows and races Scottish Deerhounds and Silken Windhounds and loves to run, climb, and kayak.

Dr. Grant-Beuttler has been the recipient of:
• the California Physical Therapy Associations Faculty Research Award in October 2016,
• the Unit Faculty Excellence Award from Chapman University in recognition of excellence in teaching, creative/scholarly, and service in April 2018,
• the Valerie Scudder Award from Chapman University in recognition of outstanding achievement in teaching and research/creative work in May 2018,
• the Dissertation Award from the Pediatric Section of the American Physical Therapy Association in February 2006.

Research interests:
The focus of Dr. Grant-Beuttler’s translational research is the development of technology to provide effective feedback to improve motor learning on the development of posture and gait, specifically toe walking. Along with her Bioengineering partner, Dr. Grant-Beuttler is the inventor of the Smart System technology to provide clinical tracking and intervention for children who toe walk.
