Our Agency

Retro Investigations is a premier private investigation company, specializing in defense of businesses that have been sued in ADA Handicapped Violation lawsuits.


Our investigators have over 85 years of collective experience. We're large enough to handle any investigation and small enough to care about each and every one of our clients.


We offer private investigation services to attorneys, businesses, and the general public. Along with asset searches and judgment enforcement, we specialize in background investigations, process service, pre-marital and boyfriend/girlfriend screening, skip tracing, and much more.  If our agency cannot provide you with the service you need we have the resources to assist you in fulfilling those needs.


Maggie Green is our company's founder and lead investigator. After a successful 22-year career in law enforcement, Ms. Green founded Retro Investigations in 2008. She is an expert in all aspects of private investigation to include civil and criminal.


At Retro Investigations, we proudly serve the Inland Empire, surrounding counties, and all of California. Our mission is to provide honest, truthful, and outstanding private investigation services to all our clients.
