Pleasanton Private Investigator Services, Built Around Surveillance
If you need a private investigator in Pleasanton, Bear Witness has been documenting the truth for California clients since 1996. Pleasanton is a city of about 78,000 people in Alameda County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.
Whether you suspect a cheating spouse, need evidence for a custody or support case, are dealing with a questionable workers’ compensation claim, or represent a client who needs court-ready surveillance, our Pleasanton investigators plan each case around the subject’s real routine and document it with time-stamped video.
Surveillance Specialists Serving Pleasanton
Most investigations come down to one question: what is really happening? A private investigator in Pleasanton answers it with surveillance video, photos, and a written timeline.
Mobile Surveillance
We follow the subject by vehicle through Pleasanton 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.
The average commute in Pleasanton is about 34 minutes, so work-related surveillance often means following a route, not waiting at one address.
