She also led the successful completion of multi-million-dollar annual giving, capital and membership campaigns for:

  • Crozer-Keystone Health System: to support the renovation and expansion of emergency departments and cancer treatment centers for five community hospitals, community health screenings, and support services and educational programming for patients and their families.
  • Natural Lands: to protect open space via direct land purchases and conservation easements, provide routine care and maintenance for 43 nature preserves, and host outdoor recreational programs for the community.
  • Nemours Children's Health: to support the expansion of the pediatric emergency department, equipment upgrades for children with mobility issues, biomedical research and patient care spanning five states, two hospitals and 80 primary and specialty care practices.

She serves on various boards within the Greater Philadelphia region including College Possible - Philadelphia, Advised Fund Committee of The Community’s Foundation, Grant Professionals Association – Southeastern PA Chapter, Visit Delco PA, Women in Transition, and Zonta International – Philadelphia Chapter. In 2021, she was elected to serve as Co-Chair of the Pennsylvania Public Horticulture Coalition, which advocates on behalf of arboreta and public gardens throughout the Commonwealth.
