Private Investigators In Philippines

OSI’s cadre of Philippines private investigators come from diverse backgrounds, most with degrees in criminal justice, but all with Bachelor’s Degrees and Philippines private detectives licenses, which are required for all commercial investigation companies operating in the Philippines. Their experience levels range from 5 years to over 30 years! Our General Manager, Mr. Mike O. Domingo, is also a graduate of the Pinkerton Investigations Academy in the United States and was previously awarded the Investigator of the Year Award, Asia-wide, out of 14 offices, for Pinkerton Asia Ltd., a subsidiary of Pinkerton U.S.A. Additionally, both he and our Manager for Intellectual Property Rights investigations, Mr. Alvin B. Ambion with 25 years of investigative experience, serve as Consultants to the Philippine National Bureau of Investigation, the lead agency for the protection of Philippine Intellectual Property Rights. Our Director of Operations, Mr. Giovanni “Vanni” Parado, has over 30 years of investigative experience and is considered the premier Philippines private investigator for the investigation of smuggling activity, as well as seizure operations of smuggled goods.Philippines detectives

While OSI’s Philippines private investigators have been lauded by numerous Western corporations for their superior results over the years, our senior Western Manager, Mr. Jeffrey A.

He is multi-awarded by both the U.S. and Philippine governments. His awards include, but are not limited to, Commander, USAF Office of Special Investigations (OSI) Outstanding Detachment of the Year in Worldwide Competition in 1987 at the U.S. Embassy – Manila, and Pinkerton Investigations’ Investigative Manager of the Year in 1997, while the Philippine Country Manager for Pinkerton.

He has served over ten years as the Chairman of the Intellectual Property Rights Committee of the American Chamber of Commerce of the Philippines.

Intellectual Property Rights

OSI has investigated several thousand IPR infringers and successfully raided over 2,500 illicit manufacturers and major importer/distributors, Philippine-wide, since 1992. And their success rate hovers at just under 98% over the last 22 years, a significant accomplishment in an industry known for significant corruption.


Commercial Investigations

While OSI's three senior managers have many years of investigative experience throughout Europe, the Americas and other areas within S.E. Asia, they have over 70+ years of such experience and investigative contacts throughout the Philippines. And, they have established a proven and successful track record as reflected by their client list outlined on the client page of this website.


Security Risk Management

OSI's Security Risk Management division supports the protection initiatives of major international and local corporations doing business throughout the Philippines. In-country operational regions include the major high risk areas in Mindanao, where current activities include performing in-depth security and political risk assessments, security program audits, VIP protection operations, and counter insurgency collections.
