Jon grew up in the beautiful Rogue Valley of Southern Oregon. He attended The Oregon Institute of Technology studying Mechanical Engineering.
During summers Jon worked for the forest service on trail crews and as a wildland firefighter. He could not pass up the opportunity to be a part of the Wilderness trail crew after graduation which brought him to Winter Park, Co. Jon found a career path in Civil Engineering in Winter Park, starting with a foundation of engineering design, and transitioning to construction services. He moved to Denver to continue advancing his career in construction engineering.

“With ERC, I am building upon my experience in construction management and engineering design on a variety of challenging projects.”

When not at the office or in the field, Jon prefers to spend his free time rafting, backpacking, hunting, fishing, gardening, and cooking.
