Andrew Sidman has been defending financial services companies for a long time and he still loves it. He is passionate about his relationships with existing clients and developing relationships with new clients.  Every case is different but Andrew’s process for success is always the same.  At the outset of each matter, Andrew works closely with in-house counsel or business representatives to develop incisive strategies and themes. His aim is to be a strong advocate for his client and, at the same time, be fair, transparent, and build rapport with regulators and opposing counsel.  His overall goal is to implement the case’s strategic plan with excellence.

Andrew is the head of the firm’s financial institutions regulatory defense practice.  Andrew specializes in representing broker-dealers and their personnel in investigations by the SEC, FINRA and other SROs and state regulators.  In addition, he oversees a significant portion of the firm’s financial institutions litigation practice and tries complex and large exposure cases.

Andrew enjoys participating in Financial Institutions industry professional development. He is the co-chair of the ABA’s Securities Litigation Committee’s Subcommittee on Self-Regulatory Organizations and State Securities Regulators, which presents several panels a year on various topics of interest.  He has been a panelist at the SIFMA Compliance & Legal Society Annual Conference for the past 15 years and has spoken at a number of SIFMA regional conferences. In addition to helping to supervise certain of the firm’s pro bono activities, Andy provides pro bono services to No Greater Sacrifice, an organization that supports the children of fallen and wounded veterans through scholarships and other educational opportunities.
