Growing up, I played sports every season. It was baseball in the summer, plus any camp my friends and I could find. Then soccer and basketball in the fall, and winter, soccer and track in the spring. I lived for recess and gym class.

After graduating from Lawrence High School in 2005, I had no clue what I wanted to do with life. I took a year off school and worked multiple part-time jobs. I quickly got overweight and out of shape. Seeing others in my family battle lifestyle-related health problems, I decided to try working out. One of my jobs was at a recreation center, and I found my way into the weight room there.

I enjoyed working out, a lot.

In 2007, I began a personal trainer education program at Pinnacle Career Institute. The 10-month program was an accelerated exercise science program with an emphasis on 1-on-1 training. I graduated with honors, and moved to Las Vegas to teach for Professional Fitness Institute.

It was while working with PFI, that I was introduced to the concepts of CrossFit. It embodied all of the concepts I enjoyed when I first found exercise and wellness, while also bringing back the fun I remembered having when I was playing sports and in gym class. CrossFit is like adult P.E. class that brings a real sense of play to a community of individuals who may never cross paths in everyday life.

Finding CrossFit changed my approach to my own training, and to the training I was offering my clients. I coached in multiple locations in Las Vegas and in Lawrence, after moving back to Kansas.

I began coaching CrossFit full time in 2011, after completing the massage therapy program at Pinnacle Career Institute. During this time I also taught the personal training program at Wellsprings Allied Health. I opened Jayhawker CrossFit in 2014.

Scott began his journey with CrossFit about three years ago, when a friend invited him to check out Jayhawker CrossFit. Scott immediately fell in love with the high-intensity interval training that Jayhawker CrossFit had to offer. He realized that it was the perfect combination of cardio and strength training, which he had worked hard to find a balance between for many years.

Scott’s passion for personal training and teaching CrossFit stems from several years spent working at the University of Kansas Hospital. After taking care of patients with medical disorders and sicknesses that could have been easily managed or even eliminated through proper physical fitness, Scott decided to take a step toward preventive “medicine”. After 2.5 years, Scott has finally been able to use the methodologies of CrossFit and healthy living to make an impact on the lives of people living in Lawrence and the surrounding areas.
