Our Team
Mario Martínez
Mario Martínez has fought for farm workers since 1999, when an Equal Justice Works fellowship brought him to the United Farm Workers of America. The son of farm workers, he picked grapes in Southern California as a boy — an experience that still drives his work. In 2015 he co-founded Martínez Aguilasocho Law, Inc. Over his career he has represented low-wage workers in nearly every agricultural industry in California and in states across the country, recovering more than $25 million in stolen wages and helping win the first heat-illness protections in the nation and overtime rights for California's farm workers. He also serves as General Counsel to the UFW.

ALRB (2017) 3 Cal.5th 1118 and Tri-Fanucchi Farms v. ALRB (2017) 3 Cal.5th 1161.

Edgar Iván Aguilasocho
Edgar Iván Aguilasocho has represented farm workers since 2013, beginning as a staff attorney for the United Farm Workers of America, where he served as lead trial counsel in the largest hearing in the history of California's Agricultural Labor Relations Board — 105 hearing days and 130 witnesses. A member of UC Irvine School of Law's inaugural class, he co-founded MAL in 2015 and now litigates wage-and-hour class actions, labor matters, and cases combating forced labor and human trafficking in agriculture. He also serves as General Counsel to the UFW Foundation. The grandson of a Bracero, Edgar carries his family's field work into every case he takes.

Staff AttorneyBrenda Rizo
Brenda Rizo grew up in Corcoran, in the heart of the Central Valley, watching her farm worker parents come home shortchanged on pay and denied water and shade. That injustice set her course. She earned degrees in ethnic studies and political economy from UC Berkeley, then her law degree from Kern County College of Law — rising at MAL from paralegal to attorney. Her work spans union-organizing fights and People v. Efrén Álvarez, one of California's first agricultural labor-trafficking prosecutions, where she worked directly with survivors from the start.

Lizbeth Valdez
Lizbeth Valdez is MAL's lead investigator. A graduate of the Escuela Comercial Cámara de Comercio (ECCC) de la Roma in Mexico City, where she earned her Licenciatura en Mercadotecnia (bachelor's degree in Marketing), she was shaped by community radio in Sonoma County — where she co-hosted Voces de Mujeres on KBBF 89.1 — and found her calling organizing alongside the United Farm Workers, from strawberry and tree-fruit campaigns to North Coast wine-grape contracts. She has helped drive victories against wage theft, labor trafficking, and sexual harassment in the fields. For Lizbeth, every worker who finds the courage to step forward is a win.
Lead Investigator
Eulogio Donato
Eulogio Donato brings a lifetime of organizing to MAL's work for farm workers. From San José de las Flores, Mesones Hidalgo, Oaxaca — and rooted for 28 years in Greenfield, California — he worked the fields himself and lived the injustices that foremen inflicted on workers. That experience pushed him to the front lines. As a community volunteer, he brought organizations and government agencies together to educate farm workers about their rights, and helped win change for Greenfield's Indigenous community against racial discrimination. As an organizer with the United Farm Workers, he secured a union election and contract at George Amaral Ranches and brought many D'Arrigo workers into full union membership. He became an organizer and investigator to keep standing with farm workers against the injustices they face every day.
Investigator
Johany Barragán keeps MAL running. Originally from Michoacán, she worked the Bakersfield and Porterville orchards to pay her way through UC Merced, where she earned a B.A. in Spanish literature and helped found a support organization for undocumented students. She began her career helping unaccompanied immigrant children win asylum, then joined MAL and was promoted to Operations Manager. She builds the internal systems that free the firm's attorneys to focus on their cases — and works to extend MAL's reach to farm workers across the state.
