I began with the Exercise Coach as a client in February 2009. At 45 years old I had reached an all time high weight and as an avid golfer I could no longer finish 18 holes of golf. Because of severe back issues, which led me to therapy and pain, management consisting of many types of injections I had consulted with a spine specialist and was contemplating the possibility of having back surgery.

Fortunately for me, a friend of mine recommended that before I have surgery to check out a new place owned by a friend of hers, The Exercise Coach. I am forever grateful that I did. Almost 50 pounds later I never did have that back surgery and today happily will play 36 holes of golf. The Exercise Coach program had such a profound impact on my quality of life that I made a new career out of it.

I started working for my new friend in December of 2010 and shortly after we decided to open two Exercise Coach studios together. I enjoyed a successful twenty-three year career in the manufacturing business, but I can tell you it never was as personally rewarding as my time with The Exercise Coach.

The ability to impact each and every client who walks through our doors in a positive way is the most motivating and rewarding experience one can have. The beauty of The Exercise Coach is that because of our “Smart Technology” we can help people achieve their fitness goals no matter what those goals are and no matter where they are starting.

Lead Trainer

I have been in sports since I was young and have enjoyed how team sports have shaped my character. I have grown as a person exponentially by involving myself with exercise throughout my life. This has led to my strong personal desire to show others their own blueprint for success in life.

After graduating high school, I ran as a member of Team Illinois as one of twelve competing against the Midwest region. I recently graduated from North Central College with my degree in Exercise Science. I was also a member of North Centrals cross-country that was ranked number one in the nation. I am currently attending Benedictine University pursuing my Masters degree in Clinical Exercise Physiology.

Working at The Exercise Coach has been an amazing experience. It allows me to be a positive influence in impacting the quality of people’s lives.

Personal Trainer

I have recently graduated from North Central College with my degree in Exercise Science. Having been part of the North Central National Championship Cross-Country team as well as their track team, has taught me a lot about the discipline and dedication necessary to reach my athletic potential. In addition North Central has provided me with a strong educational background that is allowing me to pursue my Master’s in Clinical Exercise Physiology at Benedictine University.

My motivation for training other people comes from knowing that there is greatness inside all of us. Drawing from knowledge in the classroom, real-life experience and The Exercise Coach program, it is my goal to help clients become stronger and live a healthier life.

I graduated from Western Illinois University with a Bachelors of Science in Kinesiology with an emphasis in Exercise Science and a minor in Dance in 2009. I started dancing at the age of 4 and danced my way through college. I was the captain of Western Illinois Dance Team from 2007-2009. Since college I have spent most of my time in a clinical setting, the gym, and various running trails. I have worked in health care for the past 5 years. I am very passionate about helping people achieve their fitness goals and personal goals. I like to spend my free time hiking, running, camping, fishing, cooking, and spending time with my family. I love being a personal trainer for the Exercise Coach! Most importantly I love instructing our methods of safe, effective exercise and nutrition!
