King Brothers Woodworking was founded in 1948 by Edward King and his two brothers in Union Gap, Washington. The initial business effort revolved around the manufacture of windows, but soon expanded into the manufacture of cabinets and millwork for commercial and residential customers.

In 1976, the business was assumed by a new generation of King Brothers. Gary and Curtis King have grown the company to 48 employees on a multi-facility campus that is the largest of its kind in Central Washington.

In 2005, the business was added to the Kesselring Holding Corporation family of companies and is poised for further expansion and success. Today, the company has added the production of solid surface countertops and pre-hung wood doors, but focus remains on cabinetry and millwork.
