RG COWAN DESIGN BUILD TEAM
Ryan Cowan
CEO I Owner
Ryan Cowan grew up in the Midwestern United States and was mentored by his father Robert E. Cowan. Robert E. Cowan owned and operated Cowan Homes, a custom home building company, from 1977 to 2005. Ryan has 20+ years in the construction industry and has operated as a Design Builder and General Contractor on the western slope of Colorado since 1999. In 2005, Ryan began pursuing a better understanding of Green Building practices and the science of cold climate construction methods through continuing education and involvement in Built Green Colorado and the Energy Star program. In 2008, RG Cowan Design Build designed and built its first Energy Star, Built Green Colorado certified home, achieving a five star Energy Star rating on this home and certifying it through the Built Green Colorado program. Still seeking a better understanding of Sustainable Design and construction, in 2009 Ryan left the Grand Junction area to attend CU-Boulder to pursue a degree in Environmental Design. Having completed the Environmental Design degree program in 2012, Ryan returned to the western slope of Colorado in 2013 to re-establish RG Cowan Design Build and to pursue his love of design and home building.
“For me, pursuing additional education is a journey of understanding how our environment is changing and what we should be doing about it. The facts are telling us to act and find new ways to think and do. It is important that we begin to accept the scope of this problem and the implications for the natural world, our kids, and future generations to come. We need to learn how to adjust our lives, our thinking and our businesses to this new paradigm. The idea that massive change doesn’t have to come to us through mandate is important to me. I believe that as determined, creative people, we can educate ourselves and each other to find new ways of living in this world. It is by caring about our planet and thinking of the quality of life for all, that we can make a world where future generations can thrive.”
Suzanne Hanzl
Chief Operating Officer
A Northern California native turned Coloradan, Suzanne made her way to the Grand Valley to pursue her education at Colorado Mesa University, where she earned two degrees and her husband, Barry. In 2024, she completed her lifelong dream of building a family home for her husband and their two children, Jordan and Rayna, alongside an ADU—affectionately known as “The Barn”—for her parents, Jack and Babette, on the same parcel of land. When she is not wrangling her two kids, elderly parents, three dogs, 27 chickens or two horses, she seeks tranquility in trail running, hiking, cooking and entertaining friends. With a diverse background as a two-time small business owner, house flipper, REALTOR®, real estate investor, builder, and operations manager, Suzanne brings a wealth of experience to the team. Her goal is to help harmonize the already exceptional team at RG Cowan Design Build while learning from a master in the building industry.
