Costa Rica Investigations, S.A.

(Serving Central America since 1999)

Our firm was founded in 1999 by legendary San Francisco private investigator Seth Derish and former judicial investigator Carlos Valverde because they envisioned a Central American consultancy that was oriented towards serious civil and business investigations. The agency has continuously served in this capacity since inception and their reach continues in all Central American nations. With the addition of attorney Jorge Gonzalez Mendez in 2008, the firm truly can support almost any type of investigative need in the Americas.

Our investigators provide thoroughly researched and detailed reports compiled with both public databases and our impeccable private sources. We carefully review and analyze information from dozens of public and private databases, and industry sources and produce a comprehensive and useful report to satisfy your information needs.

Mr. Seth Derish is the co-regional director for Central and South America for the Council of International Investigators, a prestigious international association with members in more than 50 countries. He is also a lifetime member of the World Association of Detectives, the largest and oldest association in the world. His 40 years in the industry have led him to the four corners of the globe. He was outside investigator for the Financial Crisis Inquiry Commission, a U.S. congressional commission tasked with investigating the Great Recession; was sent to Latin America by the U.S. Southern Command to investigate military improprieties; and was lead investigator assigned to investigate assets on a former Latin American president who allegedly stole over $200 million.
