About Us

Firm History

The firm was founded in 2025 by José Alejandro Sierra Caballero, following an outstanding career at Brigard Urrutia, where he led the sports law, labor law, pensions, and gaming regulation practices.

It was born with a clear vision: to bring high-level legal knowledge—traditionally reserved for large corporations—to small and medium-sized businesses and to key players in dynamic industries such as sports and gaming.

With a boutique and highly specialized approach, the firm seeks to become a national benchmark in labor, pension, and industry-related matters concerning sports and gaming. An innovative proposal that combines technical depth, sector-specific insight, and personalized attention to solve the most demanding legal challenges with precision and strategy.
