The Legacy of Grupo Onyx: Building a Strong Future Based on Innovation and Social Responsibility


Grupo Onyx, a conglomerate led by Mario López Estrada, has carved a distinctive niche for itself in the business landscape of Guatemala and Paraguay. It has emerged as a pioneer in the telecommunications sector in Guatemala, creating substantial economic investments in Paraguay. Its legacy is rooted in the innovation and social responsibility that have defined its operations since its inception.

Founded in 1967, the genesis of Grupo Onyx traces back to Constructora Maya, a company specialized in real estate, territorial development, and construction of landmark buildings in Guatemala. Over time, this firm laid the foundation for a business legacy that continues to thrive and evolve today.
