San Geronimo Private Investigator Services, Built Around Surveillance
Bear Witness is the private investigator in San Geronimo that families, attorneys, and businesses call when they need facts, not guesses. San Geronimo is an unincorporated community of about 560 people in Marin County. We are a veteran-owned, California-licensed firm (PI #18755), and surveillance is what we do best.
Our San Geronimo 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.
San Geronimo Surveillance Investigations: Our Specialty
Most investigations come down to one question: what is really happening? A private investigator in San Geronimo answers it with surveillance video, photos, and a written timeline.
Mobile Surveillance
We follow the subject by vehicle through San Geronimo 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.
San Geronimo is spread out (about 400 people per square mile), so subjects drive nearly everywhere. Mobile vehicle surveillance, often with two investigators, does most of the work here.
Commutes in San Geronimo average about 18 minutes, so routines tend to stay local — which helps when we are documenting a pattern over several days.
In a community of about 560 people, an unfamiliar car gets noticed quickly. We keep observation windows short and well planned.
