Who I Work With...

Individual Donors & Families

Making effective philanthropic investments can be time-consuming, difficult work. I help reduce the workload for individual donors, donor-advised fund contributors, and family foundations by assisting with strategy development, research, grantmaking, and grants management.

Foundation Clients

I work with foundations to strengthen their grantmaking by conducting landscape analyses, researching promising practices, assisting with strategy development, and assessing impact.

Corporations & Industry Groups

I’ve worked with developers, CSR leaders, and industry associations to design and implement double bottom line strategies that both further business goals and grow social impact.

Kellogg Foundation, Workforce Solutions Capital Area, and the Workforce Matters funders network, among others.

From 2008 to 2014, Sarah served as a grantmaker and program director at the Community Foundation for the National Capital Region, where she oversaw a portfolio of more than $7 million in grants, served as an advisor to corporate and individual donors, and led the Greater Washington Workforce Development Collaborative, a joint grantmaking initiative of several Washington, DC area foundations. Sarah’s work experience also includes stints with the National Skills Coalition, the National Governors Association Center for Best Practices, the Austin/Travis County Community Action Network, United Way for Greater Austin, and Apple.

She has served on a variety of nonprofit boards, volunteered with the Peace Corps in Bangladesh, and was a member the District of Columbia’s Workforce Investment Council from 2011-2015. In her spare time, you’ll most likely find her in the garden, on a yoga mat, or exploring the great outdoors with her family.
