Top-Rated Los Angeles Private Investigator

Welcome and thank you for stopping by. We understand requiring the services of a Los Angeles Private investigator is not what most folks regularly do. Whatever your reason is, please know we are great listeners, licensed California Private Investigators, and we’re here to help you, as we’ve have helped countless others. Worldwide Intelligence Network has been conducting Private Investigations in Los Angeles for thirty years.


Allow us to tell you about our Los Angeles Private Investigation company, which may help you in your decision making as to which LA Private Investigator to select. Worldwide Intelligence Network is known as a superb Private Detective Agency in Los Angeles.  Our three decades of investigative experience, and concern for our client’s welfare has attributed to us being ranked among the Best Private Investigators in Los Angeles. The publishers of Vogue, Vanity Fair, and The New Yorker ranked us among the Five Best Private Investigators in America. We also invite you to peruse some of our reviews from real clients below.


Over the past thirty years, we have undertaken some extraordinary investigative challenges. The majority of those investigations were conducted in Los Angeles. Others were investigated in New York City, and several were performed out of the USA. One such case involved the embezzlement of two hundred and forty-nine million dollars from a French Bank. Another investigation involved a Federal criminal case where the FBI charged our client with committing bribery of a Government Agent. The Judge dismissed the Government’s case because we proved the Government’s key witness committed perjury.  Please click this link to see additional testimonials about more of our challenging investigations from “REAL CLIENTS.”


We listen very carefully to every inquiry we receive. Potential clients need not be nervous about discussing their issue with us because everything you tell us is absolutely confidential, whether you assign your case to us or not. What sets us apart from many other Los Angeles Private Investigators is that we will not accept any investigative request that we feel will not benefit a potential client.

Our Los Angeles Private Investigators have 30 years of experience investigating infidelity cases often referred to as catching cheaters. Those cases require the services of top-notch professional surveillance investigators who have logged thousands of surveillance hours working in the field. These men and women surveillance investigators are dedicated professionals who are phenomenal at accomplishing one of the most challenging jobs an investigator does, which is surveilling a subject without being detected. They are absolutely discrete and trustworthy.


We have been very fortunate to work with some of the best and exceptionally brilliant attorneys in Los Angeles and New York. Every case assigned to us was never ordinary. We had to learn the essence of the lawsuit, then figure out the best investigative strategy to accomplish the assignment given to us by our attorney clients in both the civil and criminal arenas. We have worked abroad on several assignments with associate investigators with whom we’ve built great relationships with over the years.


Many of our investigations developed extraordinary outcomes by joining long-forgotten family members and old friends back together. We located many bad guys who owed money to decent people and businesses who eventually had to pay what they owed. It might be difficult to imagine, but we have indeed interviewed over a thousand witnesses and claimants involved with Workers’ Compensation claims cases for numerous Third Party Administrators on behalf of several insurance companies. We saved insurance companies millions of dollars by proving many of the claims investigation assigned to us were unfortunately bogus claims. We never approached a Workers’ Compensation claim investigation with a preconceived notion that the claimant was committing fraud. We let the case take us to the reality of an injury or simply a bogus claim.


When it comes to Background Investigations, we always obtain information that our clients did not acquire. The real shame of conducting a Background Investigation on behalf of a client who was cheated out of money or lost their business, or became involved with a significant other who took advantage of them emotionally. The saddest aspect of receiving a request for Background Investigation is that the client did not ask us to conduct the background investigation before the client became involved with that person(s) either in a personal or a business relationship. Imagine the aggravation they could have been spared.

I must admit that I was quite anxious and very apprehensive about calling a private investigator. I had conjured up a number of mental images consisting of creepy men in raincoats, fedora hats, wearing dark glasses with binoculars hangings from their necks.  My issue concerned a matter of infidelity whereby I had to determine if it was actually happening and I had to be assured of absolute confidentially because my significant other is a well-known public figure. My nerves quickly dissolved upon speaking with Barbara, the assistant director of the company.  She listened intently and immediately put me at ease because she understood how sensitive a matter this was for me. I retained her company to conduct a infidelity surveillance and at the conclusion of the surveillance assignment the information they obtained was absolutely incredible. All of my concerns were realized and documented by irrefutable video evidence.  Thanks to Worldwide Intelligence Network, I still sleep right beside my significant other who to this day remains true to our relationship. I would not hesitate to call upon Barbara, if I ever required the services of a private investigator. Nancy H. Boston, MA

I want to thank you for your superb services and to tell you that I appreciate all you have done for me over many years first by providing excellent Bodyguards for my wedding reception, and assisting me with the removal fraudulent Yelp reviews. I truly appreciate your service and have always trusted you. Kevin T., President Save-on Insurance Services, Inc. Los Angeles, CA

Robert Mann has been an incredible resource and guide through an extremely trying time for our family. We contacted Robert when we became the victims of a stalker whose erratic behavior accelerated very quickly, and we had to leave, essentially, our lives behind. Robert answered every question and every phone call, his diligence, and expertise is not something you come across often. From personal protection to discreet moving services, to helping us scout new locations and apartments to live in- Robert and his associate Chris have been absolute, consummate professionals. They both have a wealth of real-life experience protecting the safety of others. Every avenue was considered, which, as people who had never had experienced this terrible kind of privacy invasion, we had never even thought of. I highly recommend Robert Mann and the services of WINCOR to anyone who needs protection and experience in security. Thank you Robert. Jacqueline L and Athena H. Los Angeles, CA

I cannot thank you and your team enough. Your professionalism is without question. I have used many investigative firms in the past in business when I need information regarding who I am doing business with. I have never used such a firm for personal matters and I must admin that your conduct goes so over and above what others can or are able to do. I walk from this knowing the following: That you are incredible and that I have actually made a new friend who cares about and understands feelings….This above anything else makes this difficult situation easier and makes me smile. Your advice has been invaluable and only through the pleasure of meeting you to say the words of thank you can I truly express my gratitude.  Mr. S.B., Ontario, Canada

It is with great pleasure that I write this recommendation for your services. When my son had run away from home last summer, I feared I would not see him again. Thanks to you and your work, we were able to reunite within days and work out whatever issues had surfaced. Manny and Elena Gonzalez Fort Meyers, FL

I write to reiterate my appreciation for the outstanding private detective work and litigation support  that contributed to the dismissal, at trial, of all charges against our client in the bribery case of U.S. v Mullen et al.(handled out of our Los Angeles office). Your investigative deductions regarding the bogus nature of key government records proved correct, and your identification of the authorship of the handwriting on the critical, so-called “anonymous complaint” was instrumental in establishing the dishonesty of the case agent up whose testimony the government had centered its prosecution. John Lang, Loeb & Loeb, New York, NY

Notwithstanding your last minute retention, you immediately grasped the rather complicated legal principles in issue in this first impression criminal trademark case. You appeared in court well prepared, and were the best ‘second chair’ I have ever had the privilege to work with.– Phillip M Prince, Attorney at Law. Los Angeles, CA 

I recall on three separate investigations you made major contributions for our New York City clients. Your private detective investigations on an international litigation matter and the location of a significant witness immediately assisted us in obtaining a most positive result. Your finding of sequestered documents during a California matter resulted in extraordinary evidence for our client, and your location of substantial sums in hidden assets helped us to convince the defendants to agree to a favorable settlement.Martin R. Pollner Attorney at Law, New York, NY
