Lisa Mariam
Lisa Mariam, a seasoned nonprofit leader, is the new Executive Director of the Osher Lifelong Learning Institute (OLLI) at George Mason University, effective June 2, 2025. Selected from over 70 applicants after an extensive national search, Mariam will succeed Jennifer Disano, who is stepping down after 12 years to pursue her collaboration with George Mason University’s Watershed Lit Radio Literary Podcast at UpstartCrow.org and serve as a consultant for nonprofits. Disano will provide transition support during Mariam’s first week to ensure a smooth handover.
Jennifer Disano led OLLI Mason for 12 years, driving significant growth by expanding the educational program from 250 to over 500 diverse, college-level courses annually, covering literature, science, technology and the arts. She grew the staff to support this expansion, adopted hybrid learning models during the COVID-19 pandemic, and strengthened OLLI’s affiliation with George Mason University for enhanced member benefits. Disano’s focus on fiscal stability and volunteer empowerment fostered a vibrant, inclusive community, leaving a lasting legacy of lifelong learning.
Lisa Mariam brings extensive experience from her current role managing the Challenge America Program at the National Endowment for the Arts, administering grants to underrepresented communities. Previously, as Senior Director of Grants and Services at ArtsFairfax, she launched the Arts for Life initiative, expanded the Grants Program, and forged public-private partnerships. Her career began at the National Gallery of Art, organizing traveling exhibits. Mariam is also an active volunteer, serving on the Fairfax Master Arts Plan Task Force, Fairfax 50+ Plan, and the Board of the McLean Community Center.
“Lisa’s strategic vision, collaborative leadership, and alignment with OLLI’s mission make her the ideal choice to lead us forward,” said Board Chair Debbie Engleson, who led the search committee. “Her community connections and expertise in growing membership and partnerships will guide OLLI into its next chapter.”
