Windsor Construction Company was established in January 1992 with the focus of providing general contractor services for a select small client base. Ken Sinner and, now retired, Glenn Gronnerud, the founding principles of Windsor Construction, had previously managed the Northwest in-house construction subsidiary of Lincoln Property Company. They recognized the need of developers, who did not have in-house construction capability, to have a contractor who viewed the success of the developer to be as important as their own. With this understanding, Windsor Construction Company was founded on the philosophy of providing in-house construction quality services to their clients.

​After being in business for 28 years and 10,000 units later, Windsor Construction has maintained this philosophy and brought success to their clients. Creating lasting relationships spanning 10 to 28 years.
