Private Investigator in Monrovia, CA — Surveillance Is Our Specialty
If you need a private investigator in Monrovia, Bear Witness has been documenting the truth for California clients since 1996. Monrovia is a city of about 38,000 people in Los Angeles County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.

Why Surveillance Is at the Heart of Every Monrovia Case
As a Monrovia 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 Monrovia 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
Team surveillance covers multiple exits and keeps a moving subject in sight in heavy Southern California traffic.
Like much of Los Angeles County, Monrovia mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
