Two extraordinary OLLU alumnae—María Antonietta Berriozábal and María del Rosario “Rosie” Castro—embody the spirit of leadership, service, and advocacy that defines Our Lady of the Lake University. Rooted in friendship and strengthened through decades of activism, their journeys reflect a lifelong commitment to justice, education, and empowering future generations of Latina leaders.
Berriozábal, a trailblazer in public service and recipient of an honorary doctorate from OLLU in 2019 and the commencement speaker, has dedicated her life to community-centered leadership and civic engagement. Rosie Castro, who earned degrees in Spanish (BA ’71) and Sociology (BA ’75) from OLLU, is a nationally recognized activist whose work has shaped movements for civil rights and educational equity. Together, Las Dos Marías represent the power of purpose-driven leadership grounded in faith, culture, and community.
Hispanas Unidas is honored to host a sold-out celebration, Las Dos Marías: A Conversation on Friendship, Activism, & Leadership Lessons for Future Latina Leaders, featuring a special screening of a short film by Sonya Rosario, OLLU–IFCC Inaugural Artist in Residence.
