Abby Rovner

Abby Rovner, executive director

Abby Rovner served as San Francisco Friends School's Middle and High School Transition Coordinator from 2011 to 2015. In this role, she led the high school transition process, welcomed and oriented students and families new to the middle school, spearheaded the launch of the new Friends Community Scholars program, and strengthened partnerships with a range of Mission-based education and youth development agencies.

Prior to coming to SFFS, Abby started and ran "I Have a Dream" – San Francisco (IHAD-SF), a nonprofit college and career preparedness program that served a cohort of low-income youth from San Francisco's Mission and Bayview/Hunter's Point neighborhoods.  During her 12 years as Executive Director of IHAD, Abby and her team provided unwavering support to the “Dreamers” and their families as they developed the motivation and skills necessary to grow up healthy, educated, and college-bound.  

Bilingual in Spanish and English, Abby has taught Language Arts, Literature, and ESL to recently immigrated middle school students, worked in the administration of a community charter school, and served as mentor and guide for Waking the Village, a nonprofit that brought eighteen at-risk and homeless youth on a cross-country bicycle trip. She has an M.A. in Educational Policy Analysis and Evaluation from Stanford University.

Abby strongly believes in the mission of Horizons National and in the approach the program takes to strengthening elementary education, leveraging resources, and providing summer enrichment opportunities for underserved children. She feels fortunate to be building the first west coast Horizons program with the collaboration of the Mission and SFFS communities, and with the expertise and dedication of the program's talented and inspiring teachers and staff.
