During his 40-year career at FINRA, Mr. Linden held several executive leadership positions and played a key role in developing and overseeing major regulatory systems and programs.
At FINRA, Mr. Linden led the implementation of major regulatory programs and systems, including the internet-based Central Registration Depository system, used for the registration of securities firms and financial professionals, the Investment Adviser Registration Depository, BrokerCheck, and Investment Adviser Public Disclosure.

As a senior FINRA executive, Mr. Linden collaborated closely with FINRA’s Enforcement, Regulatory Operations, Office of General Counsel, and Technology teams.
