Becky Farley, MS, PhD Parkinson Disease Exercise Specialist

Dr. Becky Farley is a physical therapist, neuroscientist, and Parkinson exercise specialist, as well as the Chief Scientific Officer and Founder of Parkinson Wellness Recovery | PWR!. As an expert on exercise for people with PD, Dr. Farley delivers seminars across the world and leads our professional education faculty.  Since 2006, Dr. Farley has been sharing her expertise and has trained thousands of therapists and fitness professionals, teaching them how to more effectively work with people with Parkinson’s and to work together to best support them as they work toward achieving PD-specific functional and quality of life goals.

Becky is also the creator of PWR!Moves, a Parkinson-specific skill training approach that uses exercise to directly target specific PD symptoms to help with everyday functional mobility.  Becky teaches a variety of our exercise classes, so you’ll have the opportunity to do your PWR!Moves with their creator.  With her expert guidance, you’ll know that you’re getting high-quality workouts and gaining an understanding of how to use the PWR!Moves throughout your daily life.

Becky offers physical therapy to clients in Arizona and California wellness consultations to those outside of Arizona and California.

Outside the PWR!Gym, Becky loves cycling, yoga, and gardening (even though she’s almost certainly still thinking about new programming, our research, and advances in PD exercise science during those activities.) 😊  Becky has dreamed of an online resource like our Virtual Experience for over a decade, and is thrilled that it’s finally up and running.  She is so excited to share her knowledge, get people with PD across the US and world moving, and to help an even broader population get better and stay better with exercise.

Calli Hutchison, DPT Rehabilitation Manager

Calli first discovered her passion for working with people with Parkinson disease in 2014, as an undergrad working on a PD research study.  A few years later, she first joined the PWR! family as a physical therapy student on a clinical rotation. Calli found working at the PWR!Gym so deeply rewarding that, after graduation, she accepted a position as one of our full-time physical therapists, and she, her husband, and their three cats, Nugget, Peanut, and Khaleesi, moved to Tucson. In addition to treating clients, Calli organizes our Wellness Series and social events.

Calli offers physical therapy to clients in Arizona and wellness consultations to those outside of Arizona.

Outside the gym, Calli loves to travel—she’s been to four continents and she and her husband, Taylor, visit craft breweries everywhere they travel to.


Jennifer Bazan-Wigle, DPT, CEEAA® Physical Therapist

Jenn loves exercising and teaching exercise therapy classes (and even owns more workout clothes than regular clothes!).  Jenn teaches all kinds of classes, but you’ll see her most frequently in our cardio and circuit classes.

Jenn offers physical therapy to clients in Arizona and California and wellness consultations to those outside of Arizona and California. 

Outside the gym, Jenn and her chocolate lab, Ripp, go hiking every morning, and in the summer months, Ripp adorably finishes up by taking a flying leap into the pool.  Jenn also loves music and dancing, cooking, and traveling—two of her favorite trips ever were spent diving in Palau and exploring shrines in Nikko, Japan.
