Sarah Herlihy is Of Counsel at Arrowood LLP. She is an experienced litigator and first chair trial attorney, with a long track record of successful outcomes for her clients in state and federal court as well as in private arbitration and before state and federal agencies. Sarah’s career has been focused on complex civil litigation matters, with an emphasis on cases involving the theft of trade secrets, violations of non-compete agreements and employment disputes. Sarah has also represented clients involved in a wide variety of commercial matters, including closely-held company disputes, breach of contract and fiduciary duty claims.

Sarah has extensive experience working with individuals and companies in the financial services, pharmaceutical, biotechnology and computer software industries. Sarah’s clients rely on her ability to translate complex facts and technical issues into a narrative that is both compelling and easily understood by a court or jury.

Prior to joining Arrowood LLP, Sarah had a successful career as a commercial litigator at Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., as an employment law and trade secret litigator at the national law firm Jackson Lewis P.C. and at a boutique employment law firm.
