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.
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.
