Marty Haugh

Founder & CEO

Marty Haugh founded ProSource Building Supply in 2015 after spending nearly two decades in the building industry with two separate firms. He started with Glynn Building Products in 2000 as a delivery driver and warehouse window technician, and quickly moved up to inventory manager. After learning the technical side of the window and door business, Marty moved into the service manager role before being promoted to the sales staff. In less than a year, Marty was one of the top salespersons in the firm, focusing heavily on residential new construction and commercial retrofit projects.

In 2008, Marty was hired at Minnesota Rusco, Inc. to establish and expand the commercial window and door division. Although residential sales were still a focus, Marty’s primary area of expertise and growth was commercial retrofit projects. A strong commitment to the Minnesota Multi-Housing Association and forging relationships with property management groups helped Rusco become a major player in the Twin Cities commercial retrofit market. In addition to retrofit projects, Marty began to target general contractors and new construction applications.

In the spring of 2015, Marty opened the doors at ProSource Building Supply with the goal of strengthening the relationships he built over the years, both in the commercial retrofit arena, as well as commercial new construction. His commitment to customer service and attention to detail is reflected in the growth of the company and the repeat business ProSource has earned year after year. Within the past few years, ProSource has become one of the major players in the window and door market, thanks in large part to Marty’s customer first approach.
