Physical Therapy Assistant

Logan Hoffert P.T.A.

My name is Logan Hoffer and I am a PTA at the Elmhurst clinic. I am from a small town in central Illinois called Bradford, about 40 minutes north of Peoria where both my parents still live. I have 3 siblings, 2 sisters and 1 bother, and a niece that I absolutely adore. I achieved my bachelors degree in exercise science at Concordia University Chicago where I also competed on the track and field team.

I achieved my PTA associates degrees from Illinois Central College in Peoria, IL. I always knew I wanted to get in the physical therapy world from a young age as I had a serious knee injury when I was younger and had to go through months of physical therapy. With my continued sports injuries and physical therapy through the years, my enjoyment and interest in physical therapy continued to grow.

In my spare time I enjoy reading, listening to podcasts, spending time with my friends, traveling, and staying active. While I enjoy working with athletes, I enjoy any challenge that comes my way. My goal as PTA is to make physical therapy enjoyable and fun while also providing the best outcomes I can. I love to see the smile on someone's face when the able to return back to their normal life.
