WHY CLIENTS CHOOSE OCIS
Licensed, tested, and built for confidentiality
01
State-licensed since 2015
Operating under Texas DPS License A19977, with investigators who complete regular certification and training as methods and technology change.
02
Attorney-tested standards
Our reports and chain-of-custody practices are built to hold up under cross-examination, not just to satisfy a client.
03
Confidentiality is not a policy — it's the product
Every case is compartmentalized. What you tell us, and what we find, stays between your file and you.
04
Direct access to your investigator
No call centers or case managers relaying messages — you speak with the person actually working your case.
