Pleasant Hill Private Investigator Services, Built Around Surveillance
If you need a private investigator in Pleasant Hill, Bear Witness has been documenting the truth for California clients since 1996. Pleasant Hill is a city of about 34,000 people in Contra Costa County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.
From infidelity and custody cases to workers’ compensation fraud and litigation support, we keep our caseload small so every Pleasant Hill client works directly with the investigator in the field — and gets a clear answer, documented to the standard California courts expect.
Pleasant Hill Surveillance Investigations: Our Specialty
As a Pleasant Hill 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
We follow the subject by vehicle through Pleasant Hill and beyond, keeping distance and cover so they never know we are there.
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 Contra Costa County, Pleasant Hill mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
