Mark Johnston
Economic and Workforce Development Director
(970) 498-6624 | mjohnston@larimer.org
First Job: Cashier & Clerk at a local video store in Illinois.
How did you end up here? I knew that I wanted to work in a career where I had an opportunity to help people believe in their abilities & achieve success, whatever that success was. My careers have been diverse ranging from wilderness trip leading with youth, to providing employment & career counseling services. I currently enjoy supporting our youth & adult training teams as the program manager.
What do you love most about your current job? Lots of things! To name one, I would say I love having the opportunity to create employment & training services for people that truly make an impact. We are constantly adapting & changing to provide the best services possible.
Perks outside of work: On the weekends you’d find me with my wife & two boys doing something active. We might be hiking or biking, spending time in the garden, playing soccer or baseball, or cooking an allergy free dinner or desert in the kitchen.
Funny Quirk: I’m a fantasy baseball geek & I crunch player statistics daily. My staff know that I speak in metaphors to get my point across.
