A visionary leader who devoted her life, passion, and creativity to catalyzing groundbreaking programs, launching community-based businesses, and forging wide-reaching partnerships that fostered food security and equitable economic development.



Ciara Segura

Co-Executive Director 

Ciara’s previous experience within California’s food system spans multiple industries, including early-stage food startups, organic produce distribution, and participatory social science research. She brings with her a strong capacity to think across disciplinary borders and a dedication to thoughtful, place-based advocacy that is driven by the needs and perspectives of local residents. Food is her greatest pleasure and what inspires many of her political commitments.

Ciara joined Mandela Partners in 2018 to address competing food access and economic challenges - ensuring fair pricing for farmers who grow sustainably while simultaneously keeping the cost of healthy food affordable in underserved communities. Since then, she has led the strategic growth of the organization’s food access initiatives and farmer network, and now oversees its business and workforce development programming. In her role as co-executive director, she will continue to deepen Mandela Partners’ cross-sector partnerships and programs, and cultivate pathways for asset and wealth building in limited resource communities of color.

Ciara grew up in San Antonio, Texas, and has lived in the Bay Area for over 15 years. She holds a B.A. in Feminist Studies from Stanford University and a M.A. in Geography from the University of Texas at Austin.

Maureen has worked closely with the Board of Directors to diversify Mandela's funding revenue streams, and deepen relationships with philanthropic institutions and individual donors to support a $2.7MM organizational budget.

In her role as co-executive director, Maureen supports strategic planning and program development--including assessment of current and future initiatives, fostering innovation and areas of growth, and building new partnership opportunities on a local and national scale. 

Over the past decade, Maureen has been part of several nonprofits--serving communities nationally as well as in the San Francisco Bay Area-- to support healthier, equitable food environments. Maureen acquired her Master's Degree in Public Health from San Jose State University in 2014, and has traveled extensively across the country providing consultation with coalitions, nonprofits, and public health departments to develop multi-sector strategies that advance healthy places nationwide.

Sabine Dabady

Entrepreneurship Development Coordinator

Raised in Brooklyn, New York to Haitian Immigrants, Sabine is grateful for the path that brought her to California and now, Mandela Partners. Following several years of securing tour dates for performing arts companies, nursing injury after a bike accident was one of the catalyzing events that motivated her to pursue work connected to health, nutrition and food systems. Deeper reflections and questions about the built environment of her Brooklyn neighborhood of Flatbush sparked the necessity to ask complex questions over simple solutions. In 2015, she moved to the Bay Area to complete a graduate degree in Public Health at UC Berkeley.


In her role as Entrepreneurship Development Coordinator, Sabine collaborates with East Bay entrepreneurs in service to promoting their businesses and contributing to positive shifts in community wealth and health. Leading with curiosity, she relies on the tools that shaped her rich and diverse background working in arts administration, nutrition education, urban agriculture, and teaching. In her free time, Sabine swims regularly to keep her sane and hopes to complete a (non-competitive) swim from Alcatraz.
