Our Coaches
Certified CrossFit Instructors

The coaches at 5280 CrossFit have the ability to go beyond the movements and truly connect with our members.

They develop an awareness of each members potential and cultivate an atmosphere of success. The goal of each coach is to improve the lives, health and happiness of our members.

Coaching Philosophy:

With an emphasis on the long journey, our coaches prioritize safety and proper technique to provide the best hour of the day for our members.

Safety

Safety

We prioritize proper technique and form. Correct technique leads to efficiency and the ability to perform an exercise with the appropriate amount of relative intensity.

Hard-work

Relative Intensity

We coach each unique member to develop intensity relative to their level of increasing fitness. Intensity may look different from the outside, but every member finds a way to work hard (that’s where the magic happens).

Health

Our methodology is not random. It’s a scientifically proven, deliberate program, which helps our members move every important quantifiable health marker in the right direction.

Email Jason

Jason is an avid CrossFitter who loves the Colorado outdoors. As a husband and father of three kids (from teenagers to a toddler), he aims to stay healthy and fit for the long run. He fully intends to engage in sports, hiking, backpacking, and fly-fishing with his kids well into their adult years. Jason was a competitive gymnast through his teenage years and enjoyed running and cycling through his twenties and thirties. He discovered CrossFit at age 38 and fell in love with the community, the challenge of the workouts, and the results.

Jason doesn’t consider anything from Apple, REI, or Macallan an indulgence. He prefers shorts to jeans and would love to never wear a suit again in his life – if at all possible. Colorado has always been, and will always be his home.
