Their skill-sets range from private security, executive protection, criminal investigation and fugitive apprehensions, nationally and internationally.
ONQPI Investigators possess superior intelligence-gathering abilities and have a vast network of skilled, experienced and highly-vetted resources – locally, nationally and internationally – to gather any type of information from trustworthy sources in a timely manner.
