With over 15 years in development and nonprofit leadership, Rebekah has raised millions, led high-performing teams, and created clear and comprehensive project-based and strategic plans. 


Her experience spans mission-driven, grateful patient, and alumni-based fundraising and direct marketing. As Senior Director of Development and Community Relations at Sweetser, Rebekah combined and modernized the organization’s development and communications teams, leading to an 80% increase in funds raised in under 1 year.
