Berkeley Private Investigator

Bear Witness Private Investigators provides licensed, discreet investigation services to Berkeley and the surrounding Alameda County area. As part of Northern California, Berkeley falls within Alameda County — the East Bay, anchored by Oakland and a corridor of cities along the eastern shore of San Francisco Bay.

What Our Berkeley Clients Ask For Most

The majority of our Berkeley-area cases involve infidelity surveillance, custody and parenting-time documentation, or pre-employment and personal background checks. We also handle process serving and business investigations for local attorneys and companies. Whatever the case type, it’s built around the same core skill: documenting facts that hold up, whether that’s for your own peace of mind or for a family court filing.

Direct Access to Your Investigator

We intentionally limit how many cases we take on at once, so clients in Berkeley work with one investigator from the first call through the final report — not a call center, and not a rotating team of subcontractors. That continuity matters when a case changes quickly, which surveillance cases often do.

Serving All of Alameda County

Berkeley is one of many communities we work regularly across Alameda County, part of our coverage in Northern California. If your situation involves multiple locations — a subject who travels between cities, for example — that’s routine for us, not a complication.

Frequently Asked Questions

Do I need to visit an office in Berkeley?
No. Most clients handle everything by phone from the first consultation through the final report. If an in-person meeting is useful for your case, we’ll arrange it, but it’s never required.
What areas near Berkeley do you cover?
We work throughout Alameda County and the rest of Northern California, so a case that starts in Berkeley and moves to a neighboring city isn’t a problem. See the nearby cities we serve below.
Will I get updates while the investigation is happening?
Yes. Your investigator keeps you informed as the case develops rather than disappearing until a final report. You’ll always know where things stand.
What if I’m not sure I need a private investigator yet?
That’s what the free consultation is for. We’ll talk through your situation honestly, including whether a formal investigation makes sense or whether there’s a simpler first step.
