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.”

Shannon Affholter Resigns as Executive Director of the Master Builders Association of King and Snohomish Counties

BELLEVUE, Wash—September 6, 2017—The Master Builders Association of King and Snohomish Counties (MBA) has announced the resignation of Shannon Affholter, the executive director since 2013. A recognized and effective regional leader for the MBA, Affholter leaves a successful and flourishing organization in place. Affholter's last day will be October 6.

"During the past four years, Shannon has done a remarkable job for our association," said Mike Walsh, the current MBA president. "Shannon and his staff have developed relationships throughout the region and the MBA is on the forefront and involved in critical community issues involving attainable housing, as well as essential planning for our region's continued growth. We have been fortunate to have a professional and dedicated executive like Shannon. His achievements both external and internal have been extraordinary and will provide a strong foundation for our future initiatives. We can't thank him enough for his work!"

Affholter made his announcement last week after accepting a position as Chief Operating Officer for Oakpointe Communities, one of the Pacific Northwest's premier land and commercial development companies. "While this is an exciting opportunity for my family and myself, I recognize the hard work and commitment required to help lead a company of this stature and size," said Affholter. "While it was a hard decision to leave the MBA, I understand that my success would not have been possible without the support of my staff and the latitude granted to me by the Executive Committee and Board of Directors. I will be forever indebted to both."

Mike Walsh will welcome Erich Armbruster in January as the 2018 MBA president and board leader. "Working closely with Mike, who has been instrumental in elevating the advocacy of our association, we must now focus our immediate attention on the responsibility of finding an executive leader with the right qualities to lead our organization," said Armbruster. "The MBA has a prestigious history, and while Shannon helped transition the association to another level, both Mike and I recognize how important it is for the future of our members and the Puget Sound Region to advance our ongoing presence and influence, while working constructively and jointly with other organizations to maintain the quality of life that we enjoy here in the Pacific Northwest."
