Private Investigator in Sausalito, CA — Surveillance Is Our Specialty
Bear Witness is the private investigator in Sausalito that families, attorneys, and businesses call when they need facts, not guesses. Sausalito is a city of about 7,200 people in Marin County. We are a veteran-owned, California-licensed firm (PI #18755), and surveillance is what we do best.
From infidelity and custody cases to workers’ compensation fraud and litigation support, we keep our caseload small so every Sausalito client works directly with the investigator in the field — and gets a clear answer, documented to the standard California courts expect.
