In addition to financial services, Mary has broad experience in commercial property disputes, business tort, intellectual property, identity theft and privacy matters.

She regularly represents clients in matters pertaining to trade secret theft, covenants not to compete, and other sensitive corporate disputes. Workable approaches to dispute resolution are considered in every litigation matter, and she is creative and flexible in creating workable fee arrangements.

She is proud of her ties to Virginia, and, having clerked for the Honorable Claude M. Hilton – and having practiced in the U.S. District Court for the Eastern District of Virginia for over 25 years – she is a well-known practitioner in the Rocket Docket.

Mary is committed to cultivating professionalism and education on the rule of law and serves on the Board of Directors of the Virginia Law Foundation.
