Marissa Parker

Overview

Marissa Parker represents corporate, mutual fund, institutional and nonprofit clients as both plaintiffs and defendants in complex commercial litigation matters, with a focus in securities, investment management, health care and ERISA. Routinely serving clients in highly-regulated industries, she brings a practical, business-oriented approach to problem solving and a commitment to achieving outcomes with short and long-term value. This includes counseling clients on early case assessment, potential litigation opportunities and strategic resolution of disputes short of trial. Marissa’s practice is informed by a wide range of experience litigating cases involving securities fraud, professional liability, shareholder derivative and investor rights, fiduciary breaches, contract and indemnification obligations, wrongful death, patent infringement, and the scope of constitutional protections for religious organizations. 

Both informally and as chair of the firm’s Hiring Committee, Marissa champions the development of associate talent, diversity leadership and firm citizenship.
