    I would highly recommend Cowan Investigations.

    I have been married for over 25 years, 2 years ago things just started not feeling right, I started having suspicions that my husband was cheating. I felt trapped, I was embarrassed to talk about it with anyone. I put up with feeling … More this way for two years.
    I began researching private investigators because I was fed up with being lied to and deceived, talked to like I was crazy. I called a few investigators but I did not feel comfortable, I felt like I was talking to used car salesmen. Just before I was going to give up I called Cowan Investigations. From the minute I began speaking to Liz Cowan I began to feel comfortable, she was very genuine, caring and knowledgeable on how to proceed. Liz set up a call with Bob who I immediately could tell was very experienced and knew how to proceed.
    Over a 4 day period Bob and Joe uncovered the evidence I needed to confront the lies and other deceptions I was subjected to, which let me make the decisions I needed to make for myself. Above all I was able to regain my self respect by getting the proof I needed.
    From time Liz answered the phone until Bob and Joe finished the investigation, I was overwhelmed by the professionalism and caring they displayed towards me and the investigation.
    Thanks again Liz, Bob and Joe, you’re the best

    If there was a way to give this Gentleman ten stars, I would. Don't be mistaken by the use of the word "gentleman" he is a hound and he zeros in on the minutia of the investigation. He is a real detective with a extensive … More background in law enforcement.
    I thought that I had a really good understanding of my case and then I hired Bob Cowan. He exposed so many things that were hidden in plain sight that it blew my mind and consequently gave me much needed peace of mind.
    From the time he took my case, he kept in constant contact with me. All throughout, he explained things in way that I could understand. He was reassuring, professional and the best guy for the job!
    I am in the unenviable position of knowing what I am saying. It can and is, at times, overwhelming when you have to hire a private investigator. This usually arises from a traumatic experience and the reason why you should surround yourself with someone who knows what this experience fells like.
    I trust Bob Cowan and hope he continues to help others, like he helped me. I am grateful to have been referred to him! Thank you, Sir.
    And yes, I would be remiss if I didn't thank his wife Liz. She took my initial phone call and she knew I needed his help. She was warm and kind. Just what you need when you are faced with these situations...Thank you, Liz.

    I recently had the need to use a private investigator. After looking at several options, I decided to call Cowan Investigations. The decision to call them turned out to be one of the best decisions I ever made. I really like the fact that … More Mr. Cowan has a law enforcement background and is a former Chief of Police for Jersey City. After my first conversation with Liz Cowan I knew I had called the right people. She made me feel very comfortable when I answered all the questions she needed to get the facts regarding a very complicated situation. Liz is very thorough, caring, and very professional and usually available when I had questions. Liz and Bob make you, their priority. I NEVER had to worry if Mr. Cowan would be working on my case at the time I was promised. He was always at the location, on time, very descrete and went way above and beyond my expectations. I was informed of the progress on a daily basis and over a period of 4-5 days, had enough evidence to prove my case. The reports are very professionally written with dates and time stamped. It says a lot when my lawyer called Bob Cowan and complimented him on the great report he gave to my lawyer, to take to court. I feel the evidence gathered by Cowan Investigations and presented to the judge, by my lawyer, made a huge difference in the judge's decision. I met Mr. Cowan and shook his hand after I won the case. I highly recommend Cowan Investigations and will definitely use them again if needed. Thank you for all your hard work, you are the best!

We cannot thank Bob and Liz enough for helping us with a matter that was probably outside the realm of their normal practice. They were instrumental in assisting us in reaching out to an unscrupulous used car salesman. The individual wouldn't return our calls and obviously, did not wish to be found.Due to their tireless efforts and many phone calls, we were finally put in touch with him. With their help, the situation was fully resolved! They handled the situation with the utmost care and professionalism. We strongly recommend Cowan Investigations as they are very good at what they do!
