Service and Engineering Manager, Latin America

Guillermo serves as the sales manager for Mexico and the service and engineering manager for Latin America at FRC Global. With more than 32 years of experience in the steelmaking industry, he leads commercial efforts across Mexico and Central America and provides technical support throughout Latin America. Guillermo specializes in EAF and LF processes, refractory installation, cost-benefit evaluation, and improving steel production yields.

Before joining FRC Global in 2009, Guillermo built a robust career with companies like the Simec Group, where he held positions ranging from EAF Supervisor to Steel Mill Manager in both Mexicali and Guadalajara. He later served as Plant Director at Grupo Acerero de Zacatecas, where he successfully led the restart of a plant that had been dormant for 15 years.

Guillermo holds a degree in chemical metallurgical engineering from the University of Colima. He has continued his professional development through participation in events such as CONAC, AIST’s Steel Mill Managers' Meeting, and various courses on steelmaking processes, atomic absorption spectroscopy, and ISO 9000 auditing.

Outside of work, Guillermo enjoys starting his mornings with a good cup of coffee and cherishing weekends with his wife and children — especially watching his kids’ soccer games and going to the movies together.
