  • I would recommend this business

This service was insanely helpful and accurate. I called them in the middle of the night. Around 3 AM if memory serves. I couldn't sleep due to the situation. They were more than accommodating. I had previously called the PI service above theirs on Google, Tulsa Private Investigations, LLC but the lady that answered asked if it was an emergency and scolded me for the late hour and promptly hung up on me even though the hours stated they were open 24/7. Sulivant and Sulivant promptly answered and talked to me for an hour. Emailed me immediately and sent me the results within a VERY short period of time. The fee was also very reasonable. Much less than I had expected. I will be using their service again! Doesn't matter if it's a background check on a babysitter or to look up an opponent in a lawsuit if the need arises, or just to check out a phone number. These WILL be my go to guys from now on. Thanks a million, guys! You are soo appreciated!
