Santa Rosa Surveillance Investigations: Our Specialty

As a Santa Rosa private investigator, surveillance is the core of what we do. We document activity legally, discreetly, and in a way that holds up in court.

Mobile Surveillance

Experienced drivers who anticipate turns and freeway exits, so your subject is documented from stop to stop.

Static Surveillance

Discreet observation of a home, workplace, or business from a lawful public vantage point, documenting who comes and goes.

Two-Investigator Teams

For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.

Like much of Sonoma County, Santa Rosa mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
