Jef Krohn, Project Manager

Jef Krohn started at Sierra in 2012 working on the New Seasons in Portland. Armed with over 20 years of prior project experiences, Jef jumped right into some of Sierra’s larger Portland jobs, but has also managed multiple tenant improvements. Jef is attracted to construction because he doesn’t work the same day twice; each project comes with its own challenges and a new set of lessons. He is currently working on a multi-story self-storage facility in Portland.

Notable Projects:
Bouchon Park
Prologis PDX 20

 What brought you to Sierra? The size. It’s not so big that I would be just a number and not so small that it couldn’t withstand market fluctuations. Big enough to do the larger projects but small enough that there is still that sense of ‘family’ and pride in what we do.

If you could do another job for just one day, what would it be? A rock star.

What is your favorite pastime? Living vicariously through my kids…I coach my daughters ASA 14u softball team and my son is an avid golfer and we hit the links anytime we can.   

Tell us something that may surprise us about you. I was a golden glove boxer.
