Wallace Physical Therapy

Our Practice


Wallace Physical Therapy bringing Tucson, AZ hands on Physical Therapy since 1997.

Wallace Physical Therapy is a therapist-owned outpatient physical therapy clinic, opened in 1997, by Robert Wallace, P.T.  Our Oracle Road clinic has a well equipped rehab gym and six treatment rooms to serve you. Our practice has a distinct reputation for providing hands on quality care for your individual rehabilitation needs. 


We are most appreciative that previous patients often recommend our clinic to family and friends. We continue to treat our patients’ current rehabilitation needs, as well as empowering them with the ability to receive continued care. Our services provide our Tucson physical therapy patients with the education needed to maintain and grow their progress on their own, once their formal rehabilitation program with our clinic has come to an end. We have also added a After Care program, that offers our recently discharged patients the opportunity to continue their progress in a safe and supportive environment.

We have created a positive, supportive environment for your rehabilitation healing process, with ongoing encouragement from our friendly, understanding and compassionate staff.


We are also proud to offer a second Wallace Physical Therapy office for your outpatient physical therapy needs.  Our second Wallace Physical Therapy Clinic location is located on the northwest side of Tucson, just off W. Orange Grove and La Cholla. This clinic will also offer a rehab gym and four treatment rooms to serve you.

Marcia Ellis.jpg

Marcia Ellis, P.T.

Marcia Ellis, PT, (independent contractor) has specialized in
Vestibular Rehabilitation since 2003. If the inner ear does not
provide accurate sensory cues about movement, and the brain
can't quickly organize information sent to it by the ears, eyes,
and joints, the result can be: vertigo, dizziness, imbalance,
spatial/visual sensitivity and disorientation. The result is a lessor
quality of life and a higher fall risk. She has been in practice since
1974 and has a strong background in orthopedic manual therapy.

Katy Scott June 2019.jpg

I am a 1998 graduate of the A.T. Still University physical therapy program. The majority of my career has focused on outpatient physical therapy, involving sports medicine, post op rehab, hand therapy, and more recently a growing interest in Vestibular system related to benign paroxysmal positional vertigo (BPPV). I have enjoyed working with all ages. I am successful with sports and activity related injuries and geriatric problems.

For the last 11 years, my continued education has focused on a specific methodology for assessment and treatment of common neuro-muscular asymmetries that promote postural imbalances, and movement pattern dominance resulting in strains, sprains and joint impingement’s. Identification of the asymmetries & imbalances via specific assessment protocols enable subsequent prescription of neuro-muscular reduction and therapeutic exercises. These exercises promote muscle chain symmetry and portural balance that facilitate stability, healing and pain-free movement for regained functional capacity.
