Anna Harpst, DPT, PT

I grew up in Sugar Land, Texas, playing softball, basketball, soccer, was a member of the drum line in my high school marching band. 

I got my Bachelor’s degree in Kinesiology from Southwestern University and my Doctorate in Physical Therapy at Texas State.

As an only child, I have always been very close with my parents and grand parents. I am very passionate about helping the geriatric popluation with restoring their quality of life.  I also love helping athletes of various ages recover from their sports related injuries. I believe I bring an energetic, positive and creative approach to the table which makes treatment fun for the patients and incredibly rewarding for myself. 

In my “spare” time, I enjoy working out, playing softball, basketball, reading, spending time with friends and family, and exploring the outdoors as much as possible.

Christina Sasam, DPT., PT

I strive in a treatment plan that encompasses patient’s goals, lifestyle, and functional needs in conjunction with specialized treatment. I am certified in Trigger Point Dry Needling through the Institute of Advanced Musculoskeletal Treatment. My background includes working with adolescent, adult, and geriatric patients. I am experienced in variety of physical therapy programs including core strengthening and stabilization, pre/post-surgical rehabilitation, sports rehabilitation and work conditioning rehabilitation.

Amanda Alger, DPT., PT

I grew up in the foggy, coastal town of Half Moon Bay, CA, where I decided to attend University of California Santa Barbara for my undergraduate degree in Aquatic Biology. Despite my interest in marine biology, a couple years after graduating college I realized a career in Physical Therapy would best fit my love of movement and helping people recover from injury to stay active. I returned to school to complete my Doctor of Physical Therapy at University of St. Augustine for Health Sciences in Austin, TX.

I enjoy treating patients of all ages, but particularly enjoy working with the pediatric population. I find it fun and challenging working with kids and trying to turn therapy into a game. When I’m not in the clinic, I enjoy hanging out with my family and friends, staying active through bouldering and yoga, and spending time outdoors hiking, camping, and taking my dog swimming around Austin.

Melissa Fischer, DPT, PT

I was raised in Irving, TX and moved to Austin in 2010 to complete my undergraduate degree at the University of Texas. There I received my bachelor’s degree in social work with experience in medical social work. Upon graduation, I worked as a vision therapist, where I created and implemented therapy programs for adults and children with strabismus and visual deficits after a stroke. After a year of working as a vision therapist, I was accepted to a physical therapy program at the University of St. Augustine for Health Sciences and earned a Doctorate in Physical Therapy in 2017. I have been a member of the American Physical Therapy Association (APTA) since October of 2015. My desire to become a physical therapist stemmed from my passion for working with people. I love what I do and could not imagine a different line of work.

When I am not at work, I enjoy spending time with my significant other and family. I spend a lot of my time doing outdoor activities, including hiking, stand-up paddle boarding, obstacle course races, bouldering, and other recreational sports.
