Jeff’s building career began in 1995 and he’s simply one of the best when it comes to complex structures; it’s been said that he’s memorized every detail of every sheet of every project he’s worked on. Plus, he’s repeatedly recognized by his teammates as an exceptional mentor. He holds a BS in Construction Management from Central Washington University. Off the jobsite, Jeff’s an adventurous spirit who enjoys time with family and friends, traveling, boating, snowmobiling, off roading, fishing, and hunting in the remote wilderness.

Garth Stoppard, Jr.

Superintendent

As a second generation carpenter, Garth turned out to be a Jr. in more ways than one. Today Garth is a hard-working Superintendent who enjoys building challenges across sectors, from housing to commercial construction. Garth takes a very thorough, caring approach to getting things done on his projects, and enjoys the outdoor life in his spare time—especially riding dirt bikes, camping or doing anything on or near the water.
