I enjoyed working with Denise from the first time we spoke. She was very professional and got right to work getting me the information that I requested. Once I received it, she went over it with me and explained everything. She also gave me some options on how I could get more information should I choose to do so. I highly recommend her to anyone who needs a private investigator.

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

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.

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...

I've been using Tony and his team for the past two years and have never had a bad experience. I truly appreciate all that they do and have tried other patrols in the past.... they're second to none.

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.
