Holly Drumheller Butler

Holly Drumheller Butler is deeply experienced in counseling clients in government and internal investigations, corporate compliance and complex commercial litigation.

Holly, a principal in the Baltimore and Washington, D.C. offices, co-leads the firm’s Government Investigations & White Collar Practice Group. Holly and the team are well-positioned to help clients prepare for and respond to potential civil or criminal exposure.

She also conducts investigations in a broad array of sectors — including health care, financial services, environmental and government contracting — and has represented companies in investigations by the Department of Justice, Office of Inspector General, regulators and enforcement officials.

Holly previously served as counsel to former Secretary of Defense William S.

She has represented companies in voluntary disclosures to regulators and enforcement officials, as well as conducted numerous internal investigations on behalf of corporations, corporate boards of directors and audit committees.
