About Marcos Rodriguez Holguin

Marcos Holguin is a Partner at SR Holguin, PC. In that capacity he represents unions at every stage and in all aspects of labor and employment law matters.

At SR Holguin, PC, Marcos serves as a Litigator, an outside General Counsel to unions, a Counselor to union officers, a Collective Bargainer, a Trainer to union officers and stewards, and an Advisor with respect to government and public affairs.

Marcos is experienced representing unions in state and federal court and before administrative agencies including the National Labor Relations Board (NLRB), United States Department of Labor (DOL), and Equal Employment Opportunity Commission (EEOC). Marcos is also experienced representing unions in elections, collective bargaining, grievances, arbitrations, discipline proceedings, internal governance, and all day-to-day operations.

Further, Marcos uses his specialized education and political expertise to represent unions before elected and appointed officials and in government and public affairs. In doing so, he advocates for and against, drafts, amends, and monitors proposed federal, state, and local statutes, regulations, and ordinances, as well as crafts persuasive messaging to support clients’ positions. He also represents and advises unions’ political action committees (PACs) regarding campaign finance law and all aspects of administration.


While in college, Marcos served as a Law Clerk at Holguin, Garfield, Martinez & Goldberg, APLC. During law school, Marcos served as a Law Clerk and later as a Post-Bar Law Clerk at the Los Angeles County District Attorney’s Office, Major Crimes Division. While there, he assisted in the prosecution of some of Los Angeles County’s most complex and high-profile cases. Marcos also gained litigation experience as a member of his law school’s National Trial Team.

Early in his career, Marcos was selected as part of an exclusive group of young union-side litigators from across the country to participate in the AFL-CIO Union Lawyers Alliance’s rigorous Litigation Workshop.

Marcos is a second-generation union lawyer. He was raised in a family of many generations of union members and elected officers which instilled in him the importance of organized labor and cemented his path as a union-side attorney.

When not representing unions, Marcos can often be found spending time with his dog, or at LA Dodgers baseball, UCLA Bruins football, or LA Rams football games.
