Ethan W. Simonowitz is an associate in the Litigation and Insurance/Reinsurance groups in Crowell & Moring's San Francisco office.

Ethan's litigation practice focuses on a variety of complex commercial matters before state and federal courts, including commercial contract disputes, business torts, and copyright infringement. Ethan has participated in drafting numerous complex procedural and dispositive motions, including motions for injunctive relief, motions to compel arbitration, and motions to vacate arbitral awards.

Ethan's insurance/reinsurance practice involves counseling clients on a diverse array of direct coverage and reinsurance issues, such as late notice, policy exclusions, and policy interpretation, particularly in the context of errors and omissions and professional liability policies. 

Ethan has also developed a robust pro bono practice at Crowell & Moring. He has prepared an amicus brief to the United States Supreme Court on behalf of a nonprofit organization in support of the United States' position that ownership of certain lands reverted back to the federal government after the cessation of rail services. Currently, Ethan is representing a client seeking political asylum and handling a case for a tenant in New York Housing Court concerning allegations of nuisance and unauthorized pet ownership.

Ethan received his J.D. from the University of Pennsylvania Law School, where he served as an executive editor of the University of Pennsylvania Law Review and a legal writing instructor. Ethan earned a M.A. in Latin American history from the University of Wisconsin–Madison and a B.A., summa cum laude, in history and Latino studies from Cornell University.
