Roberta (Bobbi) Longworth is the Executive Director of the Fairfax County Park Foundation (FCPF). She leads a team of dedicated professionals and collaborates with Board Directors to support the Park Authority by raising private funds, obtaining grants and creating partnerships. During her tenure at FCPF, annual giving has increased (from $335,769 in FY 2010 to $2,414,365 in FY 2024) by more than 619%, which helps bridge the gap between public funding and Fairfax County’s needs for park land, facilities and outreach programs.

Before joining FCPF in 2010, Bobbi led the Fairfax Library Foundation where annual revenue grew fivefold over a decade. Donations helped to expand childhood literacy outreach, increase library collections, and create academic tutoring programs through Virginia’s largest library system.

Her non-profit management career began as Director of Fundraising with the United Way of the National Capital Area. She previously held private sector positions in financial accounting and corporate tax compliance at a $6 billion Fortune 500 company.

The National Capital Gift Planning Council honored Bobbi as the 2018 Jim Potter Memorial scholar for development of the FCPF Legacy Circle. In 2014, Park Foundation support helped secure the National Recreation & Park Association (NRPA) Excellence in Inclusion Award for the FCPA recreational opportunities for people of all abilities. The Partners in Preservation social media campaign raised $75,000 for Colvin Run Mill. FCPF was recognized with a 2013 NRPA Kudos Marketing Award and also selected as FCPA Trailblazer Team of the Year in both 2014 and 2024. Under Bobbi’s leadership, FCPF received the NRPA 2011 National Corporate Humanitarian Award.
