Introduction
Tammy Nguyen is a member of the Complex Commercial Disputes practice group. Tammy represents businesses and individuals involved in commercial disputes in both litigation and arbitration.
My focus
I have experience litigating and arbitrating a broad range of complex commercial matters, including contract disputes, derivative shareholder actions, class actions, trade secret misappropriation claims, restrictive-covenant disputes, consumer protection claims, real property and construction disputes, receivership matters, insurance coverage matters, and internal investigations.
My practice involves developing case strategies, drafting complaints and pleadings, conducting discovery review and responding to discovery requests and subpoenas, preparing and conducting witness interviews, drafting and arguing dispositive and procedural motions, trial preparation, settlement negotiation, and appeals.
I previously served as a judicial intern for the Honorable Colleen Kollar-Kotelly of the U.S. District Court for the District of Columbia.
Looking ahead
I am paying close attention to challenges arising during the e-Discovery process of litigation as well as corresponding technological developments. Staying updated is critical to ensure that we can manage the discovery process efficiently and to our advantage.
