Don Ferrier, CGB (Certified Green Builder), is the Owner and CEO of Ferrier Companies. As the third generation of Scottish immigrants who were stone masons and builders, he founded his business in 1984 in response to an increased need for high-performance construction methods addressing energy efficiency. Ferrier was one of the first builders in Texas to use structural insulated panels (SIPs) which provide high energy efficiency, superior strength, fire-resistance and sound insulating properties beyond typical stud construction.
