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
