Dr. Mark McMahon, DPT, OMT, CFMT
Mark is a residency-trained manual physical therapist. Graduating from Georgia State University in 1997, Mark also completed a year of Residency in Orthopedic Manual Therapy (OMT), and earned a Doctor of Physical Therapy degree, through the Ola Grimsby Institute in 2006. And in 2015, he became certified in Functional Manual Therapy (CFMT) through the Institute of Physical Art.
An avid (and occasionally injured) amateur musician and recreational runner, Mark enjoys working with clients who are passionate about their activities, whether vocational, athletic, or recreational. He believes physical therapy should be a process of self-discovery for each client, empowering them to understand their functional challenges and to help them access the tools they need to find a path to genuine healing.
He is also a longtime yoga practitioner, and began teaching yoga in 2002. He has attended a month-long course of advanced classes at the Iyengar Yoga Institute in Pune, India, and also observed the institute’s therapeutic medical classes. When appropriate, Mark incorporates yoga postures, breathing and concentration practices into PT treatment.
Mark brings deep knowledge of neuro-musculoskeletal science, along with an artful, eclectic mix of manual therapy skills and an attentive presence, to each client session. He considers manual therapy to be an educational process, using informed touch to facilitate efficient movement, which is the basis of all healing and growth.

Justin Lucke, Level III Trek Precision Fitter
Justin has been riding and racing bikes for almost 30 years. From his first mountain bike race in high school he was hooked, eventually teaching Category 1 in both road and mountain. After a 13 year detour in and out of practicing law (including a stint as a chef at Google, managing product as a "cycling guru" at a startup fitness social network, and partnering in a bike shop) Justin came back into the cycling fold full time almost five years ago at City Cycle in SF. Now that City Cycle has been acquired by Trek, Justin continues to work in the SF store as the resident fit specialist.
Bike fits have always been an obsession for Justin, trying to optimize cleat position and bike setup from the outset. After discovering the value of fit from some of the masters (including Curtis), Justin made it a point to learn from the best when he embarked on his own fitting career. Trek Precision Fit Level 1 was the first stop - the basics of using motion capture along with basic anatomy. But it was the advanced pressure mapping, anatomy and integrated diagnostic tools of Levels 2 and 3 that really kicked fitting into gear. At this point Justin embarked on an intensive internship with Curtis that brought everything full circle and incorporated the integrated tools that RIF is known for.
Justin is also very experienced with cycling fitness, having been certified as a level 2 coach by USA Cycling. He also spent his racing career focusing on improving his own performance by familiarizing himself with what does and does not make a difference. This distinction informs every fit he performs since bio mechanics on the bike is ultimately at the service of aerobic development.
Justin's bike fit practice focuses on making sure that a rider's fit doesn't get in the way of success. Whether success is defined as making the break in a race or completing a 30 mile ride without discomfort.
Dr. Katie Kennedy, DPT
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.
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.
Dr. Susan K. Casto, DPT, 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.
