Bill Tshudy
General Foreman
A true self-starter, Bill's claim that he can fix just about anything is backed by a lifetime of hands-on experience. His passion for building began at age 8, assembling bicycles, and continued through his teenage years, when he built cars and fabricated metal frames. By 21, he had entered the trades, laying the foundation for a successful career in construction supervision. Outside of work, Bill enjoys fishing and traveling the world with his wife.
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.
Sarah Cunningham
General Foreman
As a General Foreman, Sarah is known for always thinking ahead and looking out for everyone’s best interest. She enjoys the camaraderie on the jobsite and the pride that comes from persevering and building something together. A recent project of Sarah's featured a major geothermal energy system, and she used that experience to teach others at GLY about geothermal energy and how different types of systems can be used. Her hobbies include hiking, cycling, gardening, and traveling the world every chance she gets. But her favorite thing? Golden Retrievers!

Janine feels at home in the world of marketing since it combines her passion for art, writing and graphic design with her natural ability to organize, strategize, and analyze. While she enjoys her day-to-day responsibilities, facing new challenges, and the many opportunities to apply her creativity, her favorite part about her job isn’t even marketing-related; she loves working with people and getting to know everyone in the company top-down—from estimating to IT to the hundreds of hard-working craftspeople out in the field.
