ATLANTIS PRIVATE INVESTIGATIONS REVIEWS

I was nervous about hiring a PI, but from the first meeting my mind was set at ease. Michael was honest, professional and straightforward. I explained my situation, and he was able to clarify what services he could offer to assist in the situation and how it could be beneficial not only for legal action, but also to get information and answers that I could not get for myself. He returned calls and communicated in a timely manner, and I appreciated that he listened to concerns, and realistically outlined how he could help. I highly recommend his services.

We contacted Atlantis Private Investigations last year and we are happy we did. They helped us with an investigation and API did excellent work. API did a great job in answering our calls and replying to our emails in a timely manner. Michael is a great listener and has great communication skills. When the project was done I was surprised with the detailed report they created for us, it was more than expected. Their fees are very reasonable. If I need a private investigator again, I will definitely work with Michael.

Michael does a great job for us at Lawvex. He is thorough, resourceful and fast, and he always has his eye on the ball. We are completely satisfied with the work he does, and would gladly recommend him to any law firm looking for a great investigator.

I worked with Michael from Atlantis Investigations. He was kind and extremely professional. He was upfront with what I would receive and the costs. I hope I don’t need to, but I’d definitely hire him again if I had to - Jason. Reply

DARK HORSE INTELLIGENCE REVIEWS

Excellent explanation of the process and flawless execution. The examiner did everything to make me feel comfortable while making sure my results were accurate. I had a lot on the line and he came in to save the day. It's nice to have someone believe me — I can't explain how happy I am that things worked out. Thank you so much.

I'd like to extend my sincere gratitude to Dark Horse Intelligence and to Tom for their exceptional assistance during a recent situation. Tom was thorough in explaining the process and demonstrated a high level of professionalism throughout. Thanks to their support, I can move forward with peace of mind, and I would not hesitate to recommend their services to others.
