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.
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.

Naturally she signed up for our corporate DEI Committee, where she continues to make a valuable impact. As our Business Equity Specialist, Michelle provides project team guidance and support to achieve MWSBE and apprenticeship utilization goals, develops community engagement initiatives, and maintains ongoing community and industry involvement to deepen relationships within the public sector and ensure current knowledge of local, state, and federal regulation for adhering to contract requirements.
