I was iffy about hiring a private investigator! Mr. Allen walked me through everything and was very professional and helpful. He knew what he was talking about how I should go about everything.. he's the guy you wanna hire hands down :)

Outstanding Private Investigator!!! Got everything I needed and kept me informed at all times. Denise had to locate people for interviews. District Attorney was unable to locate the witnesses and Denise was able to located the witnesses. I was kept informed by either a phone call or via e-mail. Denise is very personable and gets the Job done. I look forward to a continuing business relationship with her. Everything turned out great. Denise's investigative information allowed me to get a better deal for my client. THANK YOU, Denise

James has done several forms for me and his work is outstanding. I used to be a paralegal and James has shown to me and done things that even I didn't know, saving me thousands of dollars with overpriced attorneys. He is very, very knowledgable, courteous and gives of himself. He has provided service beyond any other legal services provider that I've ever worked with, and that's a lot of firms. He also does private detective work and is excellent there as well. I HIGHLY RECOMMEND JAMES STONE ! Robert Cowart

I retained WIS to conduct a delicate social media investigation. I had an immediate response, a tailored outcome that included a thorough analysis. All the contact I had was directly with the principal, and he was fantastic at explaining the process and alerting me to the realistic outcomes that I could expect to receive. I consequently had realistic expectations - and before I actually paid for anything - about what might be possible. I did not ultiamtely find everything I wanted but it was very clear indeed that WIS went well beyond the extra mile to help me, left no stone unturned in researching the issue and looking for an answer. As an example of going beyond the extra mile, WIS kept on the matter after sending me the report that I had paid for and voluntarily provided me with an update report that did contain additional useful information. Who else would stay on the case like that? I doubt it is industry practice, but it is the way WIS actually did things for me. I found WIS very polite, very responsive, very quick, very thorough and totally objective. I would have no hesitation in recommending WIS, and I personally will not waste a second looking elsewhere if I ever needed work of the sort WIS does to be done for me. It was an excellent experience, and good value for money as well.

I called La Paz to have them do some surveillance. Once I explained why and what I wanted, they told me they could interview the people instead of costly surveillance. The investigator sent me a report that had the information I needed. I'm glad I had La Paz Research Group help me. That was money well spent.

I hired Brian and LA Intelligence for a very sensitive matter involving my cheating spouse. I have never hired a Private Investigator before so I was a bit hesitant. Although he wasn't the cheapest, his prices were reasonable and I checked him out on Yelp which made me feel even better. After speaking about my case, Brian let me know my options and gave me all the details of how he could obtain video and photographic evidence of my spouse and her whereabouts. In the first hour of his surveillance , Brian updated me with pictures of when my wife left for the gym, went to work, parked in the garage, and even going up the elevator! After work, his investigators followed her all the way from work to a hotel restaurant in swanky part of town. Brian was able to get all the video and photos that unfortunately I didn't want to see. Not only was he creative in his approach but he kept me updated regularly, and was relentless in his approach. I highly recommend LA Intelligence for any investigative need. Thanks again...

All communications from APG were immediate, clear and professional -- this was very reassuring. The security guard assigned to man the door for our private party came on time, and was very nice.

UNIT 07 was very refreshing to work with...I needed help in the form of bodyguards and I needed my former business partner investigated for fraud against myself and my new business partner. UNIT 07 was very methodical with the way every aspect of my case was handled, I only wished I could have been more involved but they got the job done and I think I was to emotional to get to close anyways. Thanks again. Robert E. C.
