With a professional career spanning over twenty-five years, he has focused his practice on advising foreign investment in both Costa Rica and Central America.

He leads multidisciplinary, cross-border teams in executing projects commissioned by multinational companies, known for his commitment and customer service reputation.

He specializes in condominium developments, both vertical and horizontal, as well as in the subdivision of large plots of land. His involvement includes due diligence investigations for purchasing future project lands, as well as the creation of schemes and investment vehicles to enable project development while obtaining all necessary regulatory approvals.

Guillermo serves as a member of various boards of directors, both of private companies and non-profit associations in the country.

He holds a Law Degree from the University of Costa Rica, an LL.M from Georgetown University, and a Bachelor’s in Economics from the University of Costa Rica. Guillermo is a member of the Costa Rican Bar Association, the National Directorate of Notaries, and the New York State Bar Association.
