He also regularly defends corporate clients, including directors and officers, in professional liability matters. While working in Washington, D.C. and Maryland, Ernie's experience practicing in more diversified areas of law gave the opportunity to broaden his reach and represent medical professionals and hospitals, as well as product manufacturers. With a constant eye toward client satisfaction, Ernie devises innovative liability defenses for each client that have proved successful in limiting any damages exposure.
