Serving New York and Florida

The Dan Ribacoff practice is built around two home markets and one international outpost. In New York, three offices cover the region: Manhattan for corporate, legal and financial casework; Garden City for Nassau and Suffolk County matters; and Harrison for Westchester, Rockland, Putnam and lower Connecticut.

In Florida, the Boca Raton office covers Palm Beach, Broward and Miami-Dade counties — Delray Beach, Boynton Beach, West Palm Beach, Fort Lauderdale and Miami — and is also the home of Delray Firearms Training. Florida's caseload skews toward elder financial exploitation, investment and romance fraud, and identity verification for international clients.

The London office in the City handles United Kingdom, European and cross-border work, including the transatlantic due diligence that neither a purely American nor a purely British firm can staff properly.
