Sienna C. Heard

Sienna Heard

Sienna Heard assists in counseling employers, including corporations and independent schools, on a range of legal issues, and drafts agreements and handbooks for clients. Sienna has enjoyed employment law since working at a small employment discrimination firm in Washington state during high school. She also has a passion for litigation, which gives her an edge on the research and drafting work she contributes for court pleadings. Her team relies on her to conduct efficient and detailed research and write convincing and legally solid arguments.

While participating in the Rising for Justice legal clinic during law school, Sienna zealously represented nearly a dozen clients under a supervising attorney by conducting legal research and writing and arguing motions in the Superior Court of the District of Columbia. The experience and skill she gained from representing clients in the clinic, serving as a senior editor on the American University Law Review, and competing on the moot court team during law school enable her to add value to the work she does for clients. Sienna is adept at breaking down complex legal information into an easily digestible summary and has a keen eye for discrete distinguishing details that can make a big difference for clients.
