Carrington Giammittorio is an associate in the Litigation Practice Group at Haynes and Boone, and she focuses on securities law defense. Carrington’s experience with both government enforcement and private securities litigation makes her uniquely suited to guide companies and individuals though parallel proceedings—helping her clients build a solid defense on all fronts. This experience extends beyond securities law to helping clients develop strategies for responding to governmental and regulatory agencies generally without compromising (or contradicting) the defense of simultaneous private litigation. She is a strong advocate for her clients and routinely manages complex legal disputes with a sharp eye and a steady hand. Carrington’s practice also extends to internal investigations, white collar defense, products liability, and antitrust.

At the University of Virginia School of Law, Carrington was the inaugural Law, Psychiatry, and Public Policy Fellow and served as an Articles Editor for the Virginia Journal of Criminal Law. She also worked as a research assistant for multiple professors, helping to edit books and design syllabi for seminars.

When not serving clients, Carrington is committed to philanthropy and mentorship. She currently serves as the national Chair of the Alpha Delta Pi Foundation Advisory Counsel. She is also passionate about fostering the professional development of current undergraduate students at her alma mater and provides advice to students interested in law school and the legal profession through the University of Virginia’s Alumni Mentoring system.
