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.

      I have used Linked Investigations for years. I had an incident with an employee in the past that taught me a valuable lesson. I now screen all potential employees. I provide Mike with basic information like a name, SSN if I have it, and an address or phone number and he can find a surprising amount of information on a person, for example, any criminal past or credit issues. The reports are thorough, timely, and worth it. I recommend him to any employer or anyone needing a background check.
