Nathan Alessi, licensed Tulsa private investigator.
Nathan Alessi founded this firm in early 2013. The work is still the same: find people, document facts, serve process, and tell the client the truth.
How it started
From research work to a CLEET license.
Alessi Investigations opened in early 2013. Before that, Nathan worked in the oil industry and in the medical field. Both jobs demanded careful research. He had already studied criminal justice and had a habit of locating people others could not. Sitting Oklahoma’s private investigator exams and background checks was the next honest step, not a rebrand.
He has been a licensed Oklahoma private investigator since 2013. CLEET is the state authority. The license is public. If you are going to hire someone to collect facts about your life, look the license up first.
How the work is done
Value, not volume. Confidential, not theatrical.
Alessi Investigations is committed to quality results and exceptional value on each case we take. We are confidential private investigators in Tulsa. The people on a file are licensed, and they use legal methods — not shortcuts that blow up in court.
Law firms trust this office with hard serves and sensitive locates. Individuals hire us for infidelity, custody, and background questions when they need a clear picture, not a pep talk. Either way, you get a proportionate plan: what we can find, what we cannot, and what it is likely to cost before the meter runs.
I will tell you if an investigation is not the right next step. Hiring us should never be the default just because you are worried.
Licensed & verifiable
