About Your Coach

I grew up in Sun Valley, Idaho playing all types of sports from soccer to baseball, snowboarding to skateboarding and everything in between. It wasn't until I moved to Hawaii in 2005 where I really began to develop a relationship with physical fitness. While living in Hawaii I had the opportunity to train with UFC fighter BJ Penn at his academy learning boxing, kickboxing, wrestling and Brazilian Jiu Jitsu . I learned what it takes to train at the top level and what sacrifices people take to achieve optimal fitness. 

After graduating from the University of Hawaii, with a degree in Business Administration in 2009, I moved back to Idaho to finish my degree in Exercise Science at Boise State. My first experience as a personal trainer was at the campus recreation center at Boise State. I had the opportunity to learn and gain experience as a trainer and develop my skills for a variety of fitness levels. I pride myself on being able to train people from all walks of life, from the professional competitor to the person who hasn't been off the couch in years.

With guidance from Chase, I am now secure in my new path to be stronger and healthier. Chase is passionate about fitness and it shows through the energy and enthusiasm every session. His easy going, friendly personality creates a relaxed, comfortable atmosphere. He makes the workouts the perfect mixture between challenging and encouraging. He also places a high value on correct form with each exercise. He motivates me to push past my limits to get results.

As I began to age, the weight slowly began to add on. My regular exercise program was no longer enough. Chase helped me get out of my rut and pushed my limits in the gym. His personalized meal plans were easy to follow and still tasted great. In six weeks chase got me back to my fighting weight! Like everything in life, sometimes you need to call in the experts. I couldn't have done it without his expertise and coaching.

Chase was just what I needed! He was encouraging, he always said "I will help you", when I felt that I couldn't push myself any further. He always made sure that my form was correct to avoid any injury. I was able to lose 10 pounds over six weeks, while changing my eating habits. I can run faster, bike faster, and I look good doing it!
