I get correspondence from people all over the world who have read my book and are successfully applying the principles. Tragically, a few had even contemplated suicide. They were in so much pain and felt so alone. It makes all the difference to know there are people that understand, care and have successful results. I only wish all those who email me from around the world could come to Canyon Rim PT where I know they would get unsurpassed care.

Cynthia is no stranger to pain!

She has had physical therapy rehab for knee problems; early stage breast cancer, surgery, and reconstruction.

Treatment philosophy

“If you run up and down a cluttered staircase, you’ll eventually get injured.  You might go to the doctor, get some medication, have x-rays and be sent to a physical therapist who speeds you to recovery.  But most patients return to that cluttered staircase of old habits.  You are the only one who can clean it up and prevent future injury.”

“My patients are quite surprised at how much they’ve learned about the powerful impact of healthy habits: Good sleeping positions, where to rest your tongue, how to breathe, position your teeth, how eyeglasses affect the body, how to sit, and how to modify furniture.”

Career moments

Cynthia recently worked with a patient who felt their jaw slide forward out of place every time they looked down. Something as simple as brushing their teeth was extremely challenging.  After just one session and a few weeks of faithfully applying the exercises and healthy habits from Canyon Rim’s Head, Neck and Jaw Stabilization program, the patient could brush their teeth and look down without difficulty.

“I once worked with a man who had terminal cancer and intense back pain.  He could barely walk.  I was sent in to evaluate the situation.  We changed things, such as his sleep position and even how he shaved.  After only several visits he could sleep through the night, shave, and walk an entire hour with his wife.  What a blessing.  It made me so happy to think that he could enjoy the time he had.  It made me realize how profound simple changes can be.”
