They have an extremely high code of ethics, both personal and professional, have never varied/deviated from this in the many years I have dealt with this Company... I have dealt with many investigators and... I have found this investigative firm to be a strong cut above everyone else.

Mark Burford | Attorney

Private Investigators come in all levels of expertise, performance, and character. I've worked with Sulivant & Sulivant Investigations for more than 3 years, and they have shown leadership in all three areas, not the least of which is character. They handle the most arduous and puzzling investigative challenges with skill and grace, and deliver on their promises. They are good for the image of Private Investigators, and great for their clients. In a field where most regard one another as competitors.

Chuck Low | RPS Operations Specialist II

I have used this PI firm to assist me in some big cases twice in the last year. If not for their diligence in locating some evidence that had been moved from Arkansas to Oklahoma my client may have been wrongly convicted of a felony.
