Having dealt with another investigative firm who delivered less than stellar results, LIA Security & Investigations LLC shows how it’s supposed to be done. They were on the “case” from the beginning, have routinely gone above and beyond and have been very thorough and communicative. They present their findings in a clear and concise manner and quickly establish a level of trust that is critical when dealing with highly sensitive matters. Great firm!

I have nothing bad to say about my experience. From the initial phone call through the receipt of the affidavit, STW Research & Investigation Services was very professional. Not only did Harry explain thoroughly how the process works, but he also worked with my schedule, and reimbursed me with no questions after I realized that I only needed to serve one party instead of two.

Ted Metzger is a great private investigator. I hired him to take pictures of me and my girlfriend on the day that I proposed to her. He was very flexible, easy to work with, and did exactly what I needed him for! The pictures turned out great, and my fiance never even knew he was there!

My case was “unusual,” to say the least. As soon as I met Nate, he approached me with understanding and professionalism. His work ethic as well as his personality are outstanding. I was somewhat nervous prior to our first meeting, however I felt at ease while talking and explaining my case in details. He always answered his phone and whatever step we were going to take next, we came to a mutual agreement. I also met some of his colleagues and they are all professional and friendly. While I cannot write about my situation specifically, I can say that I spoke to several private investigators before hiring Nate and none of them were engaged like he was. Their prices are reasonable and I am definitely going to hire him if I need to in the future. If you are looking for someone who will listen, who is reliable and who will give you a best advice, hire him!
