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.
Jeff Angehrn
Senior Construction Engineer
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.
Donovan Mabbott
Superintendent
Over the last 30 years, Donovan’s appreciation for quality craftsmanship combined with his natural ability to manage the many moving parts and pieces of a construction jobsite from start to finish has garnered trust and respect from GLY employees, trade partners, and clients. From interior build-outs to full campus developments, he approaches each project by tapping into each team member’s strengths, talents, and skillsets to develop a thoughtful plan—together. Witnessing that plan unfold successfully is his favorite part of his job. On the home front, there is never a dull moment with his four kids, granddaughter, and three dogs—each bringing joy to the family with their own unique personalities. Skylar, the littlest pup, runs the pack.
Jon Friedrichsen
Project Executive
HCC
Jon attributes his appreciation of craft and hard work to working as a carpenter for a Spokane-based general contractor while earning a BS in Construction Management from Washington State University. Since joining GLY in 1999, he’s honed his expertise as a healthcare and high-tech office project manager and team builder. When he’s not piecing together complex logistics plans, you’ll find Jon cheering on the Seattle Sounders or casting a line. If he could talk his wife into selling everything and living in a trailer down by the river, he’d be there already.
Dennis Sizemore
Cement Mason Superintendent
Dennis is the go-to guy on anything and everything concrete. At age 15, he poured and finished driveways, patios, and shop slabs. When he started at GLY at 18, he was the youngest journeyman in his union. Today, he's a concrete master who oversees projects up to one million square feet. His favorite aspect of the job is the constant change of scenery since he's not on one single project for an extensive amount of time. While concrete is a big part of Dennis’s life, he makes plenty of room for his kids, fishing, hiking, and visiting Kauai, his happy place.
