About Us

Mark and Carl started out by building a few small fences for neighbors and friends while Carl pursued a journeyman electrician license and Mark studied architectural engineering at the University of Wyoming in Laramie, Wyoming. In January 2002, Mark and Carl decided to make their dreams of owning their own business a reality. They began to advertise, and soon the calls were coming in. Initially, Mark worked full-time for the company, while Carl worked part time and kept his job as an electrician. Carl joined the business on a full-time basis in the spring of 2003.

Alan, who worked for the company from the beginning, later moved to Montana, where he started his own business. He recently returned to Powell and merged his North Dakota-based company with his brothers Wyoming based company.

SWI’s diversity has helped the company to thrive and in 2014 moved into our new facility at 988 Road 8, in Powell Wyoming. The company employs a staff of 15 to 30 employees, and it continues to grow through numerous contracts with mineral companies, state, and federal entities plus their loyal base of customers in Wyoming, Montana, North Dakota and beyond.

Mark and Alan are proud of their reputation for quality installations and excellent customer service. The company strives to be the leader in the industry with ongoing training and strong professional alliances with contractors and suppliers.
