Peter co-chairs the firm's Securities Litigation Practice. He is one of the nation's leading securities litigators and he has represented clients in well over 100 cases, investigations, and proceedings throughout the country. He has successfully defended SEC investigations, class actions, derivative suits, stock exchange proceedings, and state securities investigations, and has handled numerous FINRA arbitrations, among other matters.
Peter, through the Institutional Investor Class Action Recovery Practice, also represents hundreds of institutional investors with respect to the monitoring and evaluation of securities class action settlements. Peter has recovered over $3 billion for institutional clients. He has represented various clients in opting out of or objecting to proposed class settlements and has represented institutions as plaintiffs in various actions. In this role he participates in virtually every securities action that is filed and thus has a unique perspective when representing clients in said cases.
He has succeeded in preventing the vast majority of the dozens of clients he has represented in SEC investigations from being named as defendants or respondents. In matters where the SEC has taken action, Peter has frequently negotiated bars or suspensions, which have enabled the clients to return to their businesses or professions without undue delay.
Peter has represented many clients in FINRA arbitrations and has tried FINRA cases to successful conclusions. He also serves as an FINRA arbitrator.
He is a frequent lecturer and author on securities matters, having written hundreds of articles and papers, including co-authoring the Securities Litigation chapter in the definitive Massachusetts Continuing Legal Education publication, Business Torts in Massachusetts (2003). He has been an Adjunct Professor of Securities Litigation at the Maine Law School. He speaks at many institutional investor and securities industry forums, and is frequently quoted in the press.
After law school, he served as law clerk to the Honorable A. J. Connor (D-NH) and the Honorable Frank M. Coffin, US Court of Appeals for the First Circuit.
