Our Team

Welcome to the PREP Team!

Our team of physical therapists at PREP Performance Center has close to 10 years of experience in the sports medicine physical therapy profession and over 8 years of experience running a successful private practice.

Specializing in treating the adolescent athlete, we not only provide therapy post-injury but seek to implement pre-sport participation movement screens and our 8-week Academy Training programs that have been shown to reduce overuse and non-contact injuries. Some of the statistics below support the need for Physical Therapy Intervention at the youth sports level.

Hi! I'm Sophie, and I work at the front desk at PREP Performance Center. I graduated from Loyola University Maryland with bachelor's degrees in Psychology and Biology, and later earned my master's degree in Clinical Neuroscience from University College London (UCL). I enjoy being one of the first people our patients meet and helping make their experience at PREP a positive one. Whether I'm scheduling appointments, answering questions, or assisting with the day-to-day flow of the clinic, I love helping patients take the next step toward returning to the activities they love after an injury.

Hi, I’m Lauren! I attend UIC and a nursing major. I grew up dancing and cheered all throughout high school. I still love working out and value staying active. My favorite sport is football because my older brother played his whole life, so growing up around the sport and going to games every weekend made it so much fun for me! I love working with patients because I love connecting with people and making them feel supported while seeing their growth! Go Gophers!

Hi, my name is Eilish! I’m a junior at DePaul College Prep. I love watching baseball games (go cubs!) with my family, and I played club volleyball for 5 years! It’s one of my favorite activities to play, and I also workout regularly on the side. I grew up in Chicago, while also traveling to Iowa City for football games. My favorite part about working with patients is slowly getting to know each person that walks in, whether it’s through small side conversations or helping them through a movement!
