Rose Letwin is the founder, president, and sole funder of Wilburforce Foundation. At the heart of Rose’s philanthropy is a long-term commitment to sustaining wild places for the betterment of wildlife and communities for generations to come.
Rose enjoyed a long and successful career in technology, but she has always had a passion for animals. While volunteering in a wildlife rehabilitation center, she found herself facing the simple and devastating truth that many of these animals, once rehabilitated, had no place to go. She decided to focus her charitable efforts on habitat protection: preserving places where the welfare of animals could be prioritized. Rose founded Wilburforce Foundation in 1991 with the vision of a thriving, interconnected American West that could foster healthy wildlife. Her scientific background informed the foundation’s science-driven philosophy of employing metrics and foundational data to analyze problems and design programs for greatest impact. Her years of consulting and volunteer experiences with nonprofit organizations led to the foundation’s commitment to empowering and building up the leadership capabilities of its grantees. To date, the Wilburforce Foundation has invested more than $217 million in conservation efforts across Western North America, and is seen as an international leader in collaborative conservation. At the heart of Rose’s philanthropy is a long-term commitment to sustaining wild places for the betterment of wildlife and communities for generations to come.

Every three years we commission the Center for Effective Philanthropy (CEP) to conduct a survey of our grantees to assess our impact, interactions, and processes. The Grantee Perception Report that CEP provides to us is extremely valuable, helping ensure that we perform well in areas of particular importance to our strategic approach: building quality relationships with grantees, providing capacity building services to help them thrive, and advancing strategies that maximize our impact on the field. We’re grateful for the feedback.
