Meet the Team



Your training program starts with a motivated, knowledgeable fitness professional.

We are committed to the highest standards of excellence. You should expect nothing less. Every time you train our goal is to motivate, challenge, and educate you to be your best while you have fun along the way.

We go beyond a standard personal training certification. In addition to our university exercise science education, we better ourselves professionally through yearly continuing education (CECs) seminars and workshops. These CECs maintain our degrees and certifications, but more importantly allow us to apply the most current and effective information to all our 8 Week Edge™ programs.

Along with our desire to commit to this excellence we have an advisory board that we consult with and refer to whenever necessary.

I finally got that extra 10 pounds off. Derek motivated me to push it that little bit extra in my workouts. What a difference a few small changes make.
