With over 15 years in development and nonprofit leadership, Rebekah has raised more than $400,000,000, 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.

As Director of Development at Cummings School of Veterinary Medicine at Tufts University, Rebekah successfully led her team to increased success each year and served on the Dean’s Strategic Planning Steering Committee. Working for smaller nonprofits early in her career taught Rebekah how to capture the hearts of key partners, whether they be billionaires or neighborhood business owners.

He remained at Bottom Line for more than 11 years, holding a variety of roles including a four-year stint as Executive Director of the flagship Boston region. While in Boston, Justin completed the Institute for Nonprofit Practice’s certificate program through Tufts University and earned an MS in Nonprofit Management and Leadership from Northeastern University.
