We’re KC Company, your Northern Virginia area Pella Windows and Doors provider

In 1931, James A. Cassidy went into business for himself as a manufacturer’s agent, with several lines of “hard materials” including brick, mortar, lime, etc. Following Dad’s footsteps Alan joined the organization after completing his duty in World War II while also completing his education at Catholic University. Alan then took over as president in 1959 and sole owner in 1962. Soon thereafter, Alan acquired the local distributorship for Pella® Windows and Doors.

Under Alan’s leadership, the company grew and built Pella Windows and Doors’ status for amazing quality in the marketplace. The service area eventually expanded to include the state of Maryland, Northern Virginia, Delaware and Washington, D.C.

Kevin Cassidy came on board in 1974, representing the third generation of the Cassidy family to work for K.C. Company. Kevin was promoted to the title of president in 1987 and took ownership in 1997. Fast-forward to 2006, Most recently, Kevin shifted his role to Chairman of the Board, while promoting Stan Stokes to the position of president of all KC Companies.
