Glenn began his construction career in 1996, starting as a laborer and carpenter’s apprentice and progressing to framing homes and later operating his own remodeling company. In 2005, Glenn became a building, plumbing, and mechanical inspector for the City of Westminster, Colorado. He spent the next 13 years at the City, in roles as inspector and plan reviewer, and he earned his Master Code Professional Certification. In 2007, after teaching is first code class, he began his career in writing, teaching, and consulting, while still working full-time for the City.

Glenn has authored over 70 technical articles in publications such as “Professional Deck Builder”, “The Journal of Light Construction”, "Fine Homebuilding", and "The Building Safety Journal", as well as the ICC’s book, Deck Construction Based on the 2009 IRC. From 2011 to 2013, he took the role as Technical Advisor to the North American Deck and Railing Association, and represented the decking industry in the 2015 IRC code development process. He is a professional code educator, with audiences ranging from contractors to building officials at both public and private events.

In 2012 he began using technology to make codes more accessible and understandable, and soon opened www.BuildingCodeCollege.com, an emerging, ICC Preferred Provider, online school. For the next 6 years, he would slowly work on developing online classes and an online reputation for quality code education that dives into the "intent and purpose" of the code provisions.

In spring of 2018, Glenn took the big leap, and after 13 years with the City of Westminster he left to pursue full-time commitment to code education through BuildingCodeCollege.com. Drawing on his experience as a tradesman, contractor, consultant, and building inspector, he is able to review, discuss, and teach the standards of construction with a true understanding of the realities involved with applying them in the field.
