    Roger is excellent at his job. Right from the begining, he was responsive, attentive, and understanding. Once he started work, he kept me updated the whole time. I felt integral to the process, which I appreciated, and if you seek it, he's happy to provide insight and advice. More important that anything, he was quick with producing results. I am beyond satified with his services. If you need them, don't be a fool -- hire Roger.

    I gave Warstone $900 without any results. I did not feel like a priority with them. This was a stalking case and for me it was a priority. We scheduled an appt. for a specific purpose and then he came without the person who had the expertise in that area. We scheduled a day for him to come and then I didn't here from him on that day. When I called he said he was working another case. I was very specific about what I wanted in the initial interview and none of what we discussed was done. I wanted the house and car swept for wireless bugs. I wanted my neighbors interviewed. All I really received was two surveillance appts. I really feel it was $900 thrown away. From the reviews I read, I expected more. I now feel that I have to start over with another company. Not very professional.

    I put my heart into this investigation, I honestly expected a sincere and heart warming review after all the hard work. i understand that you been dealing with this situation for over 4 years, but we were not able to find any evidence of stalking. the attention i gave you will not compare to the attention you will get anywhere else. i sure hope you find someone that can assist you. thanks Roger

    Absolutely the best investigator out there!
    Roger Guerra met with me and had a very in depth discussion about what I needed and the timeline. He was extremely professional and his military background definitely showed. He was very focused on getting to know me and my situation and was very helpful by offering up solutions that would help me in my endeavor. Once we had all of the information laid out, he came up with a schedule and plan on how we were going to address my concerns, and immediately went to work. His use of up to date technology and communication were excellent. He provided me with information I needed very quickly and has exceeded all of my expectations. I couldn't have asked for a better investigator and will certainly use him again if the need ever arises.

    Excellent Detective with the necessary drive and determination to get the job done well and quickly
    Detective Guerra is the utmost professional as well as being a gentleman who is determined and passionate about finding answers. He took my case and handled everything very quickly and efficiently. He provided detailed information to me to take to the police and he was in contact frequently letting me know what was happening. He was very encouraging, reminding me that I would get through this and come out stronger for all that has happened. I think his military background makes him an excellent choice as he is proficient with locating answers and digging deep to connect the dots of a case. I would recommend him to anyone for their private investigative needs. He truly is the best. Jan D 1/7/17

    He is determined and competent. Don't waste money on the fakes.
    First of all as a military veteran, it was a no brainer to try Warstone Investigations. I had so many bad investigators use unethical tactics to milk me and not get the job done. I went on Thumbtack and said "let me try one more time". I was hesitant and first but when Roger assured me he was a fellow soldier, I relaxed. He did the job in 2 days for not even 1/3 of what I paid to all those other scammers. This was a child custody matter and time was of the essence. He was upfront about the fees, not for once did he take advantage of my stressful situation. He told me it would be done, that's exactly what he did. I will refer this company to everyone I know. A good private investigator is rare to find. Thanks for restoring my faith in the industry. Now I'm thinking about getting my license!
    Roger G. Dec 27, 2016

    Claudia, Let me begin by saying, that it was my pleasure to help out a fellow soldier and to know that I was able to assist you with the problems you had. I am very thankful for your kind words, and If you are even in need of a private Investigator you can always count on my company. thanks Roger

What should the customer know about your pricing (e.g., discounts, fees)?
$85 an Hour for any type of investigations and bodyguard or security guard, plus .50 cents per mile. For Process Service, I chage $75 dollars per person. I have different prices and I can always work with you, but you better believe you are dealing with the right company. As you can see I'm not afraid of my competition looking at my pricing options, and they will ask less than I'm asking, but once again its the quality of work that we provide that you need.
What is your typical process for working with a new customer?
We need to meet and find out exactly what the customer wants. Once we determine the main idea of the investigation or Security detail then we provide the customer with a comprehensive plan of action and an approximate idea on what it can cost.
What education and/or training do you have that relates to your work?
Military Police, retired out of the Army with 20 years. I received many commendations for my work in the narcotics division of the army and for the countless of undercover operations, lots of experience overseas also. I also have a Masters in Business.
How did you get started doing this type of work?
I retired with 20 years of the Army and I wanted to work for my community and be able to give work to my fellow soldiers.
What types of customers have you worked with?
Lawyers for the most part, some military and a regular civilians.
Describe a recent project you are fond of. How long did it take?
Locating a certain individual out of state, and it took me about 2 days. This could had been done in One day if the Client would had given me all the information I asked for.
What advice would you give a customer looking to hire a provider in your area of work?
Make sure you find a professional that is licensed, bonded, and insured. There is a reason why the State issues this license, we go through a intensive investigation prior to getting it approve.
What questions should customers think through before talking to professionals about their project?
do they have the money to spent on a professional? get all the facts together to provide the investigator because if you don't you are wasting your own money. And be ready to be disappointed if the Investigator does not find what you are looking for. Investigations take time and money the less you have of it, the harder it will be to conclude anything.
