About the PARR PT Method | The “3-Systems” Approach


Our team is dedicated and enthusiastic physical therapists with years of experience effectively treating complex conditions and injuries. What sets us apart from most other PT clinics is the personal attention we give each patient or athlete. Our individual, hands-on manual therapy and myokinesthetic treatments use our 3-Systems Approach to holistic health care.

The 3-Systems approach focuses on systems that are commonly overlooked that include autonomic, gastrointestinal, and vestibular systems. Each person undergoes a series of 8-10 week programs to begin building a stronger foundation required to improve compensation, pain, and function.

Our motto  is always to “Rebuild, Regain, Restore!”

Rebuild: Create building blocks necessary for fundamental movements to reduce strain associated with compensation.

Regain: Build up the strength and stability required for day-to-day activities by improving neurological motor control.

– Restore: Optimal whole-body function for peak performance

Whether it’s EDS or low back pain, we have a program for you. At the core of our physical therapy services is a thorough, whole-body assessment.

Jonathan, PT (Greater-Austin & Houston Locations) | EDS Specialist & 6-Time American Ninja Warrior Veteran and Finalist


Many of you might also know me by my nickname “The Flying Squirrel” from the hit TV show “American Ninja Warrior” (ANW). The ANW obstacle course is considered the most difficult in the world, and I was honored to be able to compete 6 seasons: (Season 5-10).

It was my sister’s struggle with a chronic neurological condition (Acute Disseminated Encephalomyelitis) that inspired me to pursue a career in physical therapy. After years of work with experts in the field, I specialized in Ehlers-Danlos Syndrome, and various other complex disorders. Also, I have the respective certifications in neurological, vestibular, orthopedic, and nerve  rehabilitation techniques.

My career began in San Antonio, Texas as a strength and conditioning coach training high-school, collegiate, and professional athletes. After graduating from Texas State University with a Bachelors in Athletic Training in 2006. I began working as an exercise physiologist for cardiac and metabolic conditions. I graduated with a Masters in Physical Therapy from the University of Texas Medical Branch-Galveston. The next 8 years consisted of working at the Houston medical center on many of the most traumatic injuries and rarest disorders worldwide.

Additionally, I’m currently one of a few rehabilitation clinicians nationwide who currently specializes in the treatment of EDS and Dysautonomia. In addition to speaking at the 2014 EDS Society Conference  regarding our highly successful “Whole Body Training” (Now known as  the “3-Systems”) approach. I’ve also continue to guest lecture for the graduate programs on various forms of rehabilitation.

When I’m not at work, I enjoy anything to do with the outdoors including hiking and paddle boarding. I also love  international travel especially Brazil and Puerto Rico so I can continue practicing my Spanish and Portuguese.

Her passion continued to grow more as she increased her knowledge of biomechanics, physiology of the healing process, and nutritional concepts associated with elite performance and recovery.

Hannah then earned her Doctorate of Physical Therapy (DPT) degree from the University of St. Augustine for Health Sciences in Austin, Texas. There, she had the opportunity to complete an extensive research on physical therapy implications for traumatic brain injuries and hypermobility syndromes related to Ehler’s Danlos Syndrome. Throughout her doctorate program, Hannah acquired advanced skills in neurological and developmental techniques for pediatrics and competitive athletes.

“Captain Duncan” | Staff Therapy Dog in Austin & Houston, Texas

Our Therapy Dog Duncan | Director of the PARR PT "K-9 Division"Meet “Captain Duncan,” our current director of the PARR PT K-9 division. As our staff therapy dog (diligently finishing his training in our Texan clinics), Duncan helps us with the occasional on-site treatment and always brightens our day.

Duncan is currently working on his resume now that already includes his certification as a “Canine Good Citizens” through the American Kennel Club (AKC). He is currently undergoing further training for his AKC Therapy Dog certification. In addition, he has begun training to alert for tachycardia for our POTS patients that will continue into 2024.

He loves his pack walk days where he gets to hike and interact with with other pups while undergoing extensive training for community activities. He also knows a few cool dog tricks if you get the chance to ask for it! His favorite one is “Plantain”…you’ll have to see it to understand!

Duncan also enjoys  being outdoors including long walks around Town Lake. He also loves playing hard with his friends at Zilker as well as paddleboarding adventures on the river.

He can be shy at first but then warms up quickly just after a few minutes of meeting. Most of the time you will see him sleeping in his bed when onsite. You will have the opportunity to meet Duncan at our  Austin location.
