Forty MBAKS members and staff traveled to Olympia Thursday, January 29 for our Annual Hill Day where we met with elected leaders to advocate for housing. The event was timed strategically just before the first policy committee cutoff, ensuring that industry voices were heard at a pivotal time for our priority bills.

MBAKS took part in 43 meetings with legislators from King and Snohomish counties, as well as the Governor’s office and Lieutenant Governor Denny Heck, to elevate our housing priorities.

“This year marks the highest number of face-to-face meetings ever held on one of our Hill Days,” said Dylan Sluder, MBAKS’s state government affairs manager. “Many thanks to our MBAKS members who showed up, shared their expertise, and helped make the day such a success!”

In addition to meetings with legislators, MBAKS had the opportunity to participate in a legislative hearing on one of our priority bills to modernize and streamline state subdivision laws, SB 5633. The bill was heard by the Senate Local Government Committee on January 29.

Special thanks to MBAKS members Mark Villwock of DR Horton and Ian Faulds of Core Design for joining MBAKS General Counsel Brian Holtzclaw in testifying on behalf of this priority legislation.

Hill Day is MBAKS’s most important advocacy event of the year. It’s an opportunity for members to engage directly with Washington state legislators and share real-world perspectives on how state policies affect housing supply, affordability, and our ability to deliver homes in our communities.

Master Builders Association Hires Kathleen Sims, Former Weyerhaeuser Executive, as its New Executive Director

Bellevue, Wash—March 1, 2018—The Master Builders Association of King and Snohomish Counties (MBAKS) announced the selection of Kathleen (Kat) Sims as its new executive director. Sims is the first woman to lead the association in its 109-year history. As the former vice president of environmental affairs, sustainability, and corporate responsibility of Weyerhaeuser Company, she is an influential leader accustomed to the building industry. She begins her new role Monday, March 5.

“Kat’s depth and breadth of experience as an executive, real estate attorney, and coalition builder will be a tremendous asset for our association,” said Erich Armbruster, the association’s board president. “She will be an excellent representative for Master Builders Association as we expand our influence with regional leaders in addressing the growth and critical housing issues facing our region. I could not be more pleased that such an exceptional leader is taking the helm.”

Sims is a seasoned attorney specializing in real estate law, with more than 10 years of in-house business management expertise. Prior to her most recent position at Weyerhaeuser, Sims worked as vice president of government affairs at Plum Creek Timber Company Inc., which merged with Weyerhaeuser in 2016. She also served as senior director of sustainability and senior director, real estate law at Plum Creek. Early in her career, Sims was a partner at Alston, Courtnage & Bassetti LLP and an associate attorney at Foster, Pepper & Shefelman LLP (now Foster Pepper), where she provided strategic legal advice to developers, landowners, and lenders.

“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,” said Sims. “I’m looking forward to forging new partnerships and locking arms with the association’s leadership, members, and staff to help solve critical issues affecting our communities.”

“Having an opportunity to engage an experienced leader with Kathleen’s credentials is a terrific outcome for our association,” said Mike Walsh, MBAKS 2017 board president and head of the executive search committee.  “Kat has sound judgement and common sense and will be an effective voice for Master Builders Association.”
