Marván, González Graf y González Larrazolo, S.C. (MGGL)

While MGGL is the largest labour and employment law boutique in Mexico, its true strength lies in the quality, depth and sophistication of its service. The firm is led by seven partners. Together, the partners combine outstanding academic credentials, including postgraduate degrees from institutions such as Harvard, Tulane, the University of Turin and the International Training Centre of the ILO, with decades of market-leading experience. This leadership team enables MGGL to advise on the most strategic, complex and sensitive labour matters faced by domestic and multinational clients.

MGGL has pursued a long-term growth strategy centred on internal talent development, institutional continuity and continuous investment in technology. Over the past 18 years, the firm has expanded from a team of 14 professionals to more than 130 lawyers and trainees, while maintaining its exclusive focus on labour and employment law.

A cornerstone of this strategy is the firm's commitment to developing leaders from within. Recent partner promotions include José Genaro Pérez Velázquez (2022), Oscar Bojorge (2024), and, most recently, Paulina Mendietta and Luis Abraham Flores Archundia, who became partners on 1 January 2026. Paulina now heads the firm's Labour & Employment consulting practice, while Luis has developed a strong practice advising on employment litigation, collective labour relations and complex workforce restructurings. Their promotions reflect MGGL's continued commitment to technical excellence, long-term client relationships and sustainable leadership development.

In parallel, MGGL has made sustained investments in technology and knowledge management, implementing advanced litigation and case-management systems that enable the efficient coordination of large, multi-jurisdictional caseloads. These investments enhance responsiveness, cost predictability and service quality for clients while supporting the firm's continued growth.

MGGL's expertise spans the full spectrum of labour and employment law, with particular strength in high-stakes litigation, collective bargaining, workforce restructurings and the labour aspects of complex M&A transactions. A defining recent mandate is the firm's representation of Atento in the Rapid Response Labor Mechanism (RRM) under the USMCA, where MGGL advised on claims brought by the telephone workers' union and coordinated closely with the Mexican Ministries of Labor and Economy, as well as international counsel. This matter has had significant legal and practical implications for Mexico's collective labour framework under international trade agreements.

The firm is widely recognised for its ability to manage complex workforce and labour risk scenarios, allowing clients to focus on their core business objectives while minimising disruption and exposure. MGGL regularly represents clients before Mexico's highest courts, including the Supreme Court, in precedent-setting labour disputes.

MGGL's large-scale litigation capabilities are a key differentiator. The firm is among the few in Mexico with the infrastructure and experience to manage thousands of employment disputes simultaneously, coordinated through its Mexico City headquarters and supported by a trusted network of local firms across more than 55 cities nationwide. Its long-standing representation of Walmart de México, handling litigation in Mexico City, Guadalajara and Monterrey, exemplifies the firm's capacity to support the country's largest employers.

Beyond contentious matters, MGGL maintains a market-leading advisory practice, assisting clients with the labour aspects of major M&A transactions, corporate restructurings and reorganisations, while maintaining strong, longstanding relationships with Mexico's principal trade unions. Recent mandates for clients including SURA, Mead Johnson Nutrition, Walmart, Nissan and Atento further reinforce the firm's leadership in this area.

MGGL is also the firm of choice for leading corporate law firms in Mexico seeking specialised labour expertise. It regularly collaborates with firms such as Nader, Hayaux & Goebel, CMS, Ritch, Mueller and White & Case, providing strategic labour and employment support in complex transactions, restructurings and market-entry projects.

The firm's client base includes many of the world's leading multinational companies across the automotive, manufacturing, retail, financial services and pharmaceutical sectors. Clients include Audi, Michelin, Walmart, Sephora, Citibank, BBVA, Levi's, Boehringer Ingelheim, EssilorLuxottica, Prudential, Johnson & Johnson, Nissan and Mitsubishi, reflecting MGGL's position as a trusted adviser to major global employers operating in Mexico.
