Ryan Cowan

Owner I General Manager

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.”

John Turner

Pre-Construction Manager

John’s love of the construction industry began before he was even born. His grandfather started a commercial construction company in 1947 and John learned early in life the importance of putting people first. John’s extensive experience in the building side of the business also revealed that there was much to be learned on the financial side. John decided to pursue education and training at Colorado State University and has over 35 years of experience in accounting and finance providing financial acumen to both local and international companies in construction, manufacturing and hospitality. John was born and raised in Grand Junction but has lived and traveled around the globe. He loves the Western Slope, and he, his wife and three sons enjoy all that the area has to offer. An avid tri-athlete, John also enjoys camping, traveling and riding on and off-road motorcycles.

Melissa Lind

Marketing Director

Melissa attributes her diverse computer skills to playing video games as a child. Her first 10 year career as a practicing LEED landscape architect honed her taste for residential and commercial design in the Bay Area and Colorado.

Her design pedigree began with her great grandfather, a Greenwich, Connecticut landscape architect who worked for the Olmsted Brothers (sons of Frederick Law Olmstead, the Landscape Architect of Central Park).

Having lived in Colorado, Arizona, Vancouver, California, Puerto Rico, New Jersey, and Spain, she and her family (husband, toddler, cat) are happy to stake a claim in Taos, New Mexico; a big-culture little-town. She is inspired by the possibilities of the wild wild web and working with amazing people.
