Francisco Reina- New Homes Manager (ext. 306)

Francisco Reina was born and raised in northwest Colorado, and had an extraordinary childhood growing up on a construction site.  He spent his days with an active imagination playing in all reaches of the house; much of the time spent under the house in the crawl space or in the attic -the forgotten areas of the home.  Francisco’s background takes him from construction, underground coal mining (BTW- clean coal is not clean), international studies, motorcycle retail, the IT industry to ultimately his life in building science and building energy performance.  His insatiable thirst for building science knowledge has led him to certifications through RESNET, BPI, and Green Advantage.  Sustainability and durability leading to a healthy environment is Francisco’s drive and his goal is to help others succeed in their comfort, safety and energy independence. Other areas of interest include anything outside, natural foods, live music, motorcycles.  When the sun is shining (or snow on a powder day), life is good.
