Don Dethlefs

Principal, Sports, Recreation and Entertainment, Denver

Born in Bridgeport Connecticut, Don considers himself lucky to have experienced, at an early age, to some of the world’s most monumental buildings – the formidable Boston Public Library, the soaring John Hancock Tower, the brutalist City Hall. It was from childhood that Don knew he wanted to be an architect.

Don believes great design engages four elements: use, function, looks, and experience. He is passionate to discover his clients’ needs which he fluently translates into flexible yet timeless designs. Don has worked on hundreds of projects around the globe, helping to elevate hundreds of thousands of athletes and engage millions of fans.

Don likes to give back to his community in his free time. He volunteers for Project Angel Heart, the Denver-based nonprofit organization focused on providing food and assistance to individuals in need. He is engaged with the AIA’s Denver chapter and sits on the board of his neighborhood park, the 80-acre Cheeseman Park.

“Architecture is about meeting the needs of client and the community, both in terms of service and in terms of creating outstanding design."
