Dr. Katie Kennedy, DPT (Doctorate in PT)

Katie earned her bachelor of science degree in biopsychology in1994 and her doctorate of physical therapy in 2003. Katie did her post-graduate training in the Australian Maitland approach to add joint mobilization to her skills and spent another year working with Ken Burns, PT and cyclist. Katie is also a certified massage practitioner.

Katie's Philosophy
Physical Therapists are movement specialists. Anatomical alignment, habitual postures, and movement patterns, if suboptimal, can lead to specific muscle weakness, joint stiffness, or overuse of other muscles. These imbalances restrict freedom of movement and cause pain, further restricting movement. Having a trained eye observe you move and feel restrictions in your muscles, fascia, and joints can reveal the problem. Manual release of these restrictions followed by training in the correct movement pattern and kinesiotaping to continue the neuromuscular re-education process will again allow and maintain free movement.

Katie was an internationally competitive gymnast as a child and a springboard diver on Stanford’s club team. In college she got hooked on triathlons. She has since run a marathon and complete 23 triathlons. Her favorite race is the Escape from Alcatraz triathlon in San Francisco.

Katie enjoys having the opportunity to rehabilitate many fire fighters, police officers and other athletes, helping them get back to enjoying their sport, activities, and life pain-free.

Mark - yoga

Mark's Philosophy
Mark considers manual therapy to be an educational process, using his informed touch to facilitate efficient movement, the basis of all healing and growth. A former professional French horn player, he was led to the PT profession as a result of efforts to solve his own postural challenges and overuse injuries associated with playing music. In his PT practice, he endeavors to give each client the space, mobility, strength and skills they need to attend to their own journey toward healing.

Mark is proud to have helped many elite cycling and non-cycling athletes accomplish their health and cycling goals, including Ben Jacques Maines and Christine Thorburn, MD, 2 x cycling Olympian, who had this to say about Mark:

"In just 3 visits with Mark, I am riding comfortably and straight on the bike again. I was amazed how quickly he discovered areas of dysfunction at sites distant (eg. my heel/ ankle) from where I thought I had a problem (my hip/ pelvis) that were limiting my improvement by my focusing only on the hip /pelvis flexibility."

- Christine Thorburn

Dr. Susan K. Casto, DPT (Doctorate in PT), CFMT

Susan holds a BS in Physical Therapy from CSU Fresno and a doctorate in Physical Therapy. She is a Certified Functional Manual Therapist (CFMT) with the Institute of Physical Arts. Susan also has training in Cranial-Sacral Therapy, and TMJ dysfunction and has completed training with Peter Edgelow, PT.

Susan became interested in Physical Therapy because of a friend who she admired. There happened to be a Physical Therapy program offered in Fresno, where she lived, and she was one of 10% of the applicants accepted that year. After graduating, Susan moved to the Bay Area, where she has raised her 2 children. She has also been employed in various Physical Therapy roles at Kaiser Permanente since 1987.
Susan also became interested in education and nearly has her teaching credential.

Susan’s PT Philosophy
Susan strongly believes that you are the best resource and advocate for your own health. Genetics are dealt to us at birth, but choices regarding environment, diet, stress, activity level, habits and outlook can result in real physiological changes in our bodies. Susan’s treatment philosophy revolves around treating underlying structural problems, not just the painful symptomatic area(s), and then instructing changes in the patient’s movement through exercise to help maintain progress.
