Master Builders select real estate attorney as association’s leader, the first woman to head country’s largest homebuilders association

Kathleen SimsFormer Weyerhaeuser Co. executive Kathleen (Kat) Sims is the next executive director of the Master Builders Association of King and Snohomish Counties.

Sims is the first woman to lead the 109-year-old group whose 3,000 member companies make it the largest residential homebuilders association in the country. She succeeds Shannon Affholter who vacated the position last fall to join Oakpointe Communities, developers of two large master-planned communities in Black Diamond and Covington.

Prior to joining MBASK, Sims was vice president of environmental affairs, sustainability and corporate responsibility at Weyerhaeuser Co. Prior to that she was vice president of government affairs at Plum Creek Timber Co. Inc., which merged with Weyerhaeuser in 2016. She also held positions at two Seattle law firms, focusing her practice on real estate.

Master Builders Board President Erich Armbruster said Sim’s professional experience will be a tremendous asset for the association as it seeks to expand its influence in addressing the region’s housing issues.

“Developing adequate housing is vital to the health of our region, and the Master Builders Association needs to be at the table as discussions are made that impact housing availability,” Sims stated in an announcement of her hiring.

Headquartered in Bellevue, MBAKS is the nation’s oldest association of local homebuilders, architects, remodelers, suppliers, manufacturers, and sales and marketing professionals.
