Our Mission
Our Story
Principled Investigations Group was founded on the principle of integrity. In a field where discretion is vital, we felt that principle was too often negotiable. We built this firm to be different.
We combined the high-level operational standards, resources, and training of federal law enforcement with the agility and client-focus of a boutique firm. The result is an agency that never compromises on methodology or ethics.
From our headquarters in Texas, we established a network of trusted assets to ensure we could deliver the truth for our clients, no matter where the facts led.
