Prior to private practice, Jonathan served as an attorney in FINRA’s Department of Enforcement for almost 14 years.

Jonathan regularly guided FINRA staff on developing investigations and examinations concerning potential violations of the federal securities laws and FINRA rules. He brought disciplinary actions against member firms and their associated persons through negotiated settlements, litigated proceedings before FINRA’s Office of Hearing Officers, and appealed before FINRA’s National Adjudicatory Council. 

Jonathan also served as in-house counsel at a large independent model broker-dealer, handling a high volume of SEC, FINRA, and state securities regulatory requests in routine, cause, and enforcement matters.
