Stacylyn Doore is a Partner in Quinn Emanuel’s Boston Office.  She divides her practice between complex commercial litigation, where she represents both plaintiffs and defendants in breach of contract, business torts, fraud, securities, trade secrets, and employment matters, and securities enforcement, where she focuses on insider trading, market manipulation, and Foreign Corrupt Practices Act investigations.  Stacylyn’s mix of experience ensures she views issues from multiple angles—considering collateral regulatory consequences in commercial cases and thinking critically about the evidentiary endgame in investigations.

Stacylyn has extensive experience managing every aspect of case development, from pre-Complaint disputes through trials and appeals.  She has appeared at trial, where she has examined and cross-examined witnesses; taken and defended dozens of depositions (both fact and expert); drafted and argued dozens of dispositive and discovery motions; and managed complex e-discovery efforts.  She works closely with clients every step of the way, offering practical advice and solutions to often difficult discovery issues. 

Stacylyn has also worked closely with expert witnesses on complex damages and statistical matters.  In a recent case, Stacylyn’s work on the damages analysis resulted in the plaintiff’s reducing the alleged damages number by over $20 million.

Stacylyn developed additional trial and appellate courtroom experience while serving as an Assistant District Attorney for Middlesex County where she prosecuted jury trials and argued evidentiary motions regularly and as an Assistant Attorney General in the Administrative Law Division of the Massachusetts Attorney General's Office.

Stacylyn has an active pro bono practice, with a focus on immigration rights of children.
