What Happens When You Call

The first conversation is free, confidential and honest. Dan Ribacoff or a senior investigator will ask what you already know, what you need to prove, and what you intend to do with the answer. That last question matters most: an investigation built for peace of mind looks very different from one built for a courtroom.

If the case is viable, you receive a written scope and a cost estimate before any work begins. If it is not viable — or if what you need is a lawyer, an accountant or a locksmith rather than an investigator — you will be told that instead of being sold a retainer.

An investigation is only worth what it can prove. Everything we produce is documented to survive being challenged.

Coverage in New York

New York casework runs from three offices. The Manhattan office at 60 East 42nd Street handles corporate, financial and litigation matters across the five boroughs. The Garden City office covers Nassau and Suffolk County — the busiest location for domestic and small-business work on Long Island. The Harrison office serves Westchester, Rockland, Putnam and lower Connecticut.

Coverage in Florida

The Boca Raton office covers Palm Beach, Broward and Miami-Dade — including Delray Beach, Boynton Beach, West Palm Beach, Fort Lauderdale and Miami. South Florida generates a distinctive caseload: elder financial exploitation, investment and romance fraud, and identity verification for international buyers and sellers.

Cross-Border

The London office makes US/UK due diligence and asset tracing a direct service rather than a subcontracted one. Beyond the five offices, a vetted correspondent network covers other jurisdictions.
