Jared Chin, PTT

My name is Jared and I was born and raised in Portland, Oregon. When I was younger, I played a bunch of different sports, but the one that stuck was gymnastics. I stayed with the sport long enough to follow my dream of being a collegiate athlete. When I was 20 years old, I got a call from the coach at Arizona State University asking if I wanted to come down and be on the gymnastics team. I took the opportunity and moved to Arizona a few months later. After living in Arizona for a few months I decided that this was my new home and that I would be staying here indefinitely. 

What got me interested in PT is a job I had coaching cheerleading. I have a lot of knowledge and experience treating and rehabbing injuries of both myself and the kids that I coached. I had reached a point where I knew I did not what to coach forever and pursuing my goal of becoming a Physical Therapist seemed like the next logical step. 

This is when I came to find Rebound. I was finishing up my degree at ASU and I needed an internship. After having a great interview with both Todd and Leslie I knew that that this was going to be a great fit for me and the next part of my journey. I have really enjoyed working at Rebound. I have found fun and friendly atmosphere of both the staff and clients to be one of the best out there. I always show up to work with a smile on my face excited to work with everyone who is coming in that day!

Outside of Rebound I am working on my application for Physical Therapy school. When I am not busy with that, I spend my time hanging out with friends, playing various sports, and going to music festivals.
