Mike's fascination with SIP panel building began in 1992, and he fully embraced high-performance construction in 2005, earning recognition as an award-winning Master Builder through SIPA in 2013. He continues to construct high-performance homes using SIPs, driven by a commitment to fulfilling his clients' housing dreams.

About Bryan

Bryan Schaefer, a Texan native who grew up in the California Bay Area, developed his hands-on skills through high school courses in woodworking, cabinet making, and auto shop. Following graduation, he gained experience in various California cabinet shops, focusing on precision, finishing, and installation. In 1994, inspired by his grandfather's success in the painting contracting industry, he embarked on his own entrepreneurial journey. In 2016, he established a construction company specializing in commercial remodeling, adopting the motto "Because the finish counts." His interest in panel building and SIPs (Structural Insulated Panels) was ignited during his work with a panelized roofing company. Bryan, living with his wife, Molly, in the East Bay, is committed to addressing the affordable housing crisis in the region and has raised four children together.
