Mario Martínez

Mario Martínez has been a farm worker rights lawyer since 1999 when he began working with the United Farm Workers of America after being awarded a two year post-graduate fellowship from Equal Justice Works. In 2015, Mario joined Edgar Aguilasocho and Tom Lynch in forming Martinez Aguilasocho & Lynch, APLC ("MA&L").  Mario has a unique appreciation for the work performed by our clients, as he comes from a family of farmworkers and himself labored in the grape fields of Southern California as a child.  

In his many years working with UFW and MA&L, Mario has engaged in the representation of low-income farm workers and other low-income wage earners in complex class actions in state and federal courts in California.  Mario has represented low wage earners in some capacity in virtually every agricultural industry in California, as well as in Florida, Washington, Oregon, and other states, including representing workers performing work in the following agricultural industries: table grape, wine grape, strawberry, raspberry, mushroom, citrus, tree fruit, flower, apple, artichoke, lettuce, broccoli, and other vegetables.  Mario currently serves as General Counsel for the UFW.

Mario graduated from UC Berkeley School of Law and has been a licensed California attorney since 1999.  Mario is admitted to the United States District Courts in the Central, Eastern, Southern, and Northern Districts of California, and to the United States Court of Appeals for the Ninth Circuit.

Edgar Iván Aguilasocho

Edgar is the grandson of farm workers and the son of unionized public-sector workers who became a lawyer to create positive change for families like his own. After becoming the first college graduate in his family, he joined the inaugural class at the UCI School of Law to receive his education in community lawyering. While at UCI Law, Edgar was deeply engaged in the effort to launch UCI as a premier public interest law school, participating directly in the formation of a number of ongoing institutions (such as the first law school newspaper -- the uRSA Voice -- and a first-of-its-kind annual negotiation and international law simulation program -- the Global Justice Summit). While there, Edgar also spent two semesters serving Orange County's immigrant community as part of the UCI Law Immigrant Rights Clinic.      

After law school, Edgar moved to the San Joaquín Valley to begin his career in community lawyering, first as a staff attorney for the United Farm Workers, and most recently as a partner at MA&L. As a staff attorney for the United Farm Workers, he worked with farm workers to negotiate collective bargaining agreements, arbitrate grievances, and litigate dozens of unfair labor practice cases. In one such case, Edgar served as lead trial counsel for the UFW in Gerawan Farming, Inc. (2016) 42 ALRB No. 1, a major victory for farm workers against California’s largest peach grower as well as the longest case in the history of California’s Agricultural Labor Relations Board, spanning 105 hearing days with 130 witnesses.

In 2015, Edgar partnered with seasoned farm worker attorneys Mario Martínez and Tom Lynch to form Martínez Aguilasocho & Lynch, a private, public interest law firm based in California's Central Valley and dedicated to the mission of improving the lives of farm workers and their families. At MA&L, Edgar primarily litigates labor matters, wage and hour class actions, and other workers’ rights cases. Edgar is also the General Counsel for the UFW Foundation, a non-profit organization that aims to empower and improve the lives of farm workers, immigrant workers and Latinos through community education, civic participation and the promotion of equitable public policy.
