  • review rating 5  This is an outstanding company with outstanding investigators! Highly professional and extremely good at what they do. The founder and owner of the company is quite famous and has been in the business for years. What's also great about this company is they have not only ex-military investigators but they also have a retired NSA Army counter-intelligence agent working with them now. I highly recommend this company for any type of Private Investigations especially in San Diego County, Orange County, and Los Angeles County. I have heard their Northern California office is outstanding as well but I have only had first-hand experience with the Southern California office which has been top notch. I went through all of the reviews for the company and I agree with all of them except for the girl that claimed they stole her money. I thought that was an interesting comment as most likely what happened is she paid them a small amount of money to probably get surveillance on something and unfortunately private investigators cannot make miracles happen and it is not like Hollywood movies where they can push a button and get video footage from inside the bedroom from 10000 miles away. So if that person does not do something sketchy or suspicious during the time frame the private investigator is watching him or her, then there's nothing that they can do about it. I don't know if I would call that stealing but I think if you want really good results from utilizing a private investigator you should allow them one full day or more to perform the investigation. That way if anything at all happens they're definitely going to be able to find it. Especially this company. They definitely perform above and beyond from what I've seen working with other PIs.
