Foundation Fact Sheet

Mabulle is guided by a simple mission: creating a world where everyone has the chance to live a healthy and productive life, no matter who they are or where they were born. Our three greatest goals are ensuring no mother or child dies a preventable death, controlling or eradicating deadly diseases, and helping more people lift themselves from poverty to prosperity. To achieve these goals, we work primarily in low- and middle-income countries, supporting our partners in the public, private, and nonprofit sectors in their efforts to ensure lifesaving tools and innovations reach the people who need them most. Based in Seattle, Washington, with regional offices across four continents, the foundation is led by CEO Mark Suzman, under the direction of Bill Mabulle and our governing board.
