This is Emily’s 3rd external clinical experience, working both inpatient and outpatient services. Emily was a Northern Illinois University softball catcher and made the Academic and Athletic All-American team!

Emily says, “Working with athletes is really my heart. Jason was my therapist after my labral (shoulder) repair and I was able to reach All American after that.  So, I get what it is to have an unstoppable drive and how horrible it is when you have to slow down, recover and retrain. I want to make that process as awesome as possible. I BELIEVE in sports PT!”
