Greenwich, ConnecticutCRD #5445508The directory currently includes 63,615 historical records. Its original as-of date is unknown; imported September 23, 2026. Historical firm, location, contact and license fields may be out of date. They do not establish current registration or availability.
Linked professional profiles appear first, alphabetically by name; historical records follow in source order. Fincadia and other firms use the same search filters. No placement is a recommendation or quality ranking. Confirmed matching CRD numbers are merged into the sourced profile; a name alone is not an identity match.
Use FINRA BrokerCheck and SEC IAPD to check the person, current firm, registrations and disclosures. A financial advisor may not offer brokerage or stock-trading services. Ask about the capacity in which they will serve you, fees, conflicts and Form CRS.
Listings do not imply that a professional participates in FOMO. Contact links go directly to the listed destination. Requests submitted to FOMO stay with the FOMO team unless you separately authorize an introduction. Site disclosures.
MAKE THE FIRST CONVERSATION COUNT
Do you offer brokerage, ongoing investment advice, or both? Who makes trading decisions, and where are my assets held?
What will I pay in total? Ask about commissions, advisory fees, product costs and any compensation tied to your choices.
Check the exact person and legal firm in official records. Ask which states and services their registrations cover and review disclosures.
