A little about me. Helping people become healthier, better, faster, stronger, and reach their optimal potential has always been one of my greatest passions. With this passion in mind, I completed my undergraduate studies at Lindenwood University where I majored in Athletic Training and Exercise Science, with a minor in Psychology. After graduating I worked as the Head Athletic Trainer at a local high school where I got to further my passion for helping clients overcome and prevent injuries. I got to work with team coaches and strength and conditioning coaches to develop training programs to help our teams perform at their peak potential while working to prevent injury. 

This was a great job and I loved every second of it. I couldn’t get enough, helping clients get back to what they love was icing on the cake. However, I always felt as though there was something more, I could be doing to help more people. So, I did a lot of research into other professions and even higher education. When I first told family and close friends that I was considering going back to school, most of them thought I had gone mad. But seeing my passion for helping others, they were all incredibly supportive, nonetheless. I honestly could not thank my parents and my wife enough for helping me to work through the planning and logistics of it all.

So, I started my search. I investigated all possible options available to me. 

Then I remember back to my childhood. I was quite an active child, and rather prone to getting myself into trouble that most often culminated in bumps, bruises, and sometimes a trip to the doctor’s office. The doctor of choice was, more often than not, an amazing Chiropractic Physician. This was a huge light-bulb moment! I started looking into Chiropractic: what all they can do, how they treat clients, how they help people, and what their philosophy on healthcare is. The more I researched Chiropractic, the more excited I got about this option! Almost everything was lining up with my outlook on client care. It was amazing! And even better, one of the best chiropractic schools in the country is only a few minutes away!
