I spoke to Frank. He was unbelievably honest and had the utmost professionalism in taking my call even though I was in a time of crisis. He gave me the information I needed to put me on the right track to resolve my issue. He could have made money off of my situation but instead saved me a lot of money. Thank you Frank and Atlas Investigations!

I recently engaged Atlas investigations to help me with a personal situation and I can't speak highly enough of Frank and his team. Frank has incredible follow-up, he is professional, discreet and also very kind. This was a difficult situation and I appreciated Frank's sensitivity. The work they did was through, detailed and they had prompt communication throughout the time they were working on my case. I highly recommend Atlas Investigations.

Frank Estrella is truly a star. I needed info for a civil rights lawsuit and he found what I had spent months on trying to find INSTANTLY. Not only that, hey, we're in the bay area so I assumed it would cost a fortune. Not at all- he did the work for a very low, unbelievable fee. He certainly is highly skilled and he works for a very fair price. He gets my highest recommendation ever!

I have hired Frank and his firm for approximately 3 separate engagements. Each time is the same professional and fast service. The most recent was a pretty complicated engagement. The firm not only delivered but delivered fast and with full confidentiality.

I went to Frank after trying to do my own research for a while, but was unsuccessful. I had two cases which were complicated.Walking in the door, I was very nervous, but he immediately makes you feel right at home. Frank’s professionalism and friendliness is outstanding! He explained very well what was going on and answered all of my questions. He is straight forward and kind and runs an extremely professionally office. I felt that I was in good hands.I was happily surprised with the amount of information he was able to provide me! It was a very thorough and confidential investigation and in a timely manner. I couldn’t be happier with the results!Thank you, Atlas Investigations!

I have not only called upon Atlas Investigation many times over the years but have referred them to others as well. They have always been upfront as to what they could and could not do working within the law. And what they charge for the services they provide. No hidden cost very professional.

Atlas Investigations is a premier private investigation organization. Contrary to an previous review, Atlas Investigations does not employ security guards and is NOT affiliated with Atlas Security. I'm a consultant and often refer clients to Atlas Investigations. Frank Estrella, owner and CEO does exemplary work and my clients have nothing less than happy with his wirk, results, ethics, integrity and ability to do the job right.

I used Atlas Investigations recently. They were very professional, discreet, and promptly responded to my needs. I was impressed with their knowledge of the family law process. Their expert testimony in court following the investigation was exceptional and I won my case. I would highly recommend Atlas Investigations.

I have been using Atlas Investigations for prospective employee back ground checks since 2012 and have been very pleased with the results. Our previous Investigator could not find history on a prospective employee. Frank produced results showing the prospective employee used fake identification on his application. Frank has also conducted surveillance for us on a several occasions with positive results.
