GAIN PI, A Professional Investigation and Consulting Agency, is a San Diego Private Investigator Agency and serves all of California from our private investigation office in San Diego, California. GAIN PI was established in the year 2000 to provide personalized investigative services for surveillance investigations, insurance fraud investigations, worker’s compensation investigations, business investigations, undercover investigations, cheating spouse or infidelity investigations and litigation research.  GAIN PI believes taking on too many cases at one time does not allow for personalized service for our clients. GAIN PI accepts a limited amount of cases at one time affording top quality personalized investigative services to private, corporate and insurance clientele. A high volume of cases would prevent us from carrying out our promise to our clients of quality, personalized service. GAIN PI never treats our clients like a number and responds to all correspondence as soon as possible.

GAIN PI is a local San Diego Private Investigation agency and does not hire outside contractors to perform assigned work in other cities or within San Diego. We do not advertise in other cities claiming to have a presence and then sub-contract out the work. When a client retains GAIN PI, GAIN PI handles the case with the same personal service given to all our clients, corporate, insurance or private. Occasionally, GAIN PI is requested by clients to travel outside of the San Diego area and within California to conduct investigations of all nature.
