Engineering Design Associates is a full service multi-disciplined consulting engineering firm founded in 2004. EDA originally started out as Patterson, Weber and Associates. PWA was a Mechanical and Electrical Consulting Engineering firm which was formed in 1978 by Harry Patterson and Duane Weber. In 2000, Kevin Schilling assumed ownership, replacing Duane and Harry when they retired. In 2004, Kevin, Jak Peden Hollinger, and Ken Hilton decided that it was time to retire the old PWA name and re-organize as Engineering Design Associates. The 3 partners and the remaining professional engineering staff provide over a hundred years of combined design experience in residential, commercial, and industrial engineering.

EDA has a professional staff of 9 including 6 professional engineers licensed in the state of Wyoming, with several maintaining registration in surrounding states in the Rocky Mountain area.
