Glenn started construction in 1998 as a laborer and carpenter’s apprentice, which evolved into framing houses and building decks, and later operating his own remodeling and deck-construction company. He then spent 13 years working for the City of Westminster, Colorado as a building, plumbing and mechanical inspector and plan reviewer, and in 2007 earned a Master Code Professional certification from the International Code Council. During this time, he also worked as a freelance writer, educator, and consultant in codes. Glenn has authored over 100 technical articles in the “Professional Deck Builder”, the “Journal of Light Construction”, “Fine Homebuilding”, “Building Safety Journal”, as well as the International Code Council’s book, “Deck Construction Based on the 2009 International Residential Code”, including a second edition based on the 2021 IRC. In 2011 he became an advisor to the North American Deck and Railing Association (NADRA), where he assisted the association with code-related initiatives and the Master Deck Professional Code certification program. He was active in the development of the 2015, 2021, and 2024 IRC, representing the decking industry. Glenn also works as a construction code educator, with audiences ranging from contractors to building officials at both public and private events. He was awarded as the 2021 Educator of the Year by the International Code Council. He is the creator of BuildingCodeCollege.com, where he is actively working to grow a catalog of on-demand courses. In 2018, Glenn left the City of Westminster to commit full time to teaching, writing and consulting in code.
