Calistoga Private Investigator Services, Built Around Surveillance
If you need a private investigator in Calistoga, Bear Witness has been documenting the truth for California clients since 1996. Calistoga is a city of about 5,200 people in Napa County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.
Our Calistoga clients include individuals facing infidelity or a missing family member, parents in custody and support disputes, employers and insurers dealing with fraud, and law firms that need evidence and testimony. What they share is a need for discreet, lawful surveillance that holds up.
Why Surveillance Is at the Heart of Every Calistoga Case
As a Calistoga 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
We hold position at the locations that matter to your case and record activity with time-stamped video.
Two-Investigator Teams
For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.
Like much of Napa County, Calistoga mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
