Ploughshares Fund transitions to new leadership in San Francisco headquarters

Elizabeth Warner appointed Managing Director of San Francisco office

SAN FRANCISCO, CA – Global security foundation Ploughshares Fund announces today, the appointment of Elizabeth Warner as managing director of its San Francisco headquarters and the departure of long-time Chief Operating Officer Philip Yun, who assumes leadership in October as president and CEO of the World Affairs Council of Northern California, a San Francisco-based organization founded in 1947 with affiliated chapters throughout the Bay Area.

"We are excited to welcome Elizabeth Warner in this new role. She will bring new energy and new ideas to our leadership and mission," said Ploughshares Fund President Joe Cirincione. "We will miss Philip greatly, but are proud that World Affairs has selected him as their new president. He will surely excel there as he has at Ploughshares Fund."

Ploughshares Fund is the largest philanthropic organization in the country devoted exclusively to the elimination of nuclear weapons. Warner, who joined Ploughshares Fund in 2012, has led the successful implementation of strategic fundraising for both the San Francisco and Washington DC offices of the peace and security foundation.

"The Ploughshares Fund mission is more important than ever," said Warner, whose new duties and responsibilities as Managing Director & Chief Development Officer will encompass executive oversight, administration and advancement of the San Francisco office, where the nonprofit was founded in 1981. "Our foundation has an incredible track record of supporting innovation, tackling gender issues, and building partnerships across the field. I’m deeply grateful for the opportunity to help lead the organization at this time, and to work side by side with our amazing staff and other leaders in the field."

Yun, who also served eight years as a member of the Ploughshares Fund board of directors led the organization through a significant period of growth, playing an influential role in the foundation’s expansion of a Washington D.C. office. As a regional expert on Asia and North Korea, Yun provided strategic guidance in the face of escalating tensions and opportunities in that region. His leadership with the historic Iran deal, N Square and the Women’s Initiative leaves a legacy of innovation and impact.

"It has been a joy to see Ploughshares Fund grow from a regional voice to a significant stakeholder in the national security field," said Yun, whose career includes working on US policy and negotiations with North Korea during the Clinton administration. "Ploughshares Fund has become a proven model for effective grantmaking and advocacy. I’m thrilled that the foundation is set for new leadership with Liz Warner, who I have been close colleagues with for years. She will take Ploughshares Fund to new heights."
