Gretchen O’Connor, PT

A native of Buffalo, NY, Gretchen graduated from Russell Sage College in Albany, NY. While taking time off to raise her four children, she coached their grammar and middle school track and field teams, trained for and completed 3 marathons. The emphasis on proper movement techniques and training with this young population allowed her to learn from and focus on normal movement patterns. Gretchen is certified in Selective Functional Movement Assessment (SFMA) and Functional Movement Screen (FMS) to be better able to identify abnormal movement patterns, get to the core of the problem and determine the best treatment option for the individual’s needs. Gretchen believes “it’s all connected”, whether in the body from the feet to the cervical spine, or in life from your physical to mental and spiritual self. The body is a complex integrated system, not “a knee problem” or “back pain” and has to be treated as such.

Ryan Carroll, PT, DPT

Ryan attended North Central College in Naperville, IL, where he graduated with honors and received a Bachelor’s degree in Exercise Science with an emphasis on wellness. Ryan received his Doctor of Physical Therapy degree from Rosalind Franklin University in 2017. During undergraduate studies, Ryan was an active member of the Health and Exercise Science Organization and participated in exercise-based classes and fundraisers for a variety of athletics and populations. These ranged from children to seniors and from the recreational walker to competitive lifter and athlete.
Ryan has also previously worked as an agility and conditioning coach, personal trainer, and strength and conditioning intern at the Bulls/Sox training academy. Ryan believes every person is an “athlete” if there is some goal they are trying to achieve and spent his time at work developing every aspect of fitness to achieve those goals. Ryan also believes every component of fitness is vital to the development of the “athlete” as a whole and for injury prevention.

Sheila Taylor, PT

Sheila Taylor graduated from Rosalind Franklin University/The Chicago Medical School in 1995 with a Bachelor of Science degree. Over the course of her career, Sheila has worked with neurological, geriatric, sports medicine and orthopedic patients. Her love is neurological as she finds these cases to be more of a challenge in piecing the puzzle together to get the patient back to function.

Growing up in Gurnee, Sheila was an athletic trainer for her high school. The head trainer asked her what she wanted to pursue in college and she was not sure but knew she wanted to work with people in a medical capacity. Sheila was then introduced to a physical therapist and after watching what he did and how he helped his patients, she knew that was her career path!

About a year and a half ago, Sheila was involved in a serious car accident and she suddenly found herself on the other side of the PT equation – she was not the patient. Sheila credits her work as a PT in giving her the insight into what a patient goes through from initial injury to rehabilitation, to coming home and getting back to work. She knows now the hard work you must put into being a patient if you want to get back to 100% – you have to put in the time and desire. Sheila’s accident gave her a better perspective and empathy for what her patients are going through but she also knows that you can get back to a functional lifestyle if you are willing to work hard.
