Our staff has a wide range of expertise in many different areas of the residential construction industry. Some are registered architects and engineers with experience in residential building science and construction technologies, energy efficient building design, and house systems such as ventilation, heating, and cooling. Others work in quality control practices, information technology, and communications. While we’re the first to admit we don’t have all the answers, our staff is passionate about learning how to improve the quality of homes, and sharing what we learn with the industry.
