Darrell is a partner with Walter | Haverfield. He chairs the firm's Antitrust and Unfair Trade practices and Creditors' Rights and Bankruptcy practice groups, and is vice-chair of the Litigation group. His practice encompasses both complex civil and white collar criminal defense litigation.

Darrell's civil practice spans several areas. Darrell advises, counsels and represents clients in all types of antitrust and unfair competition matters. He regularly performs antitrust reviews of business agreements and advises clients on strategies to avoid exposure to allegations of anticompetitive activity. He represents employers and employees in litigation over restrictive employment covenants and confidentiality agreements, including obtaining and opposing injunctive relief. He has significant experience in the law of trade secrets, including trying several such cases to jury verdict in state and federal court. He also counsels employers on structuring restrictive covenants to avoid having them judicially narrowed or invalidated.

Drawing on his experience as an instrument-rated pilot, Darrell is involved in a wide variety of aviation-related legal matters. He has defended manufacturers and home builders of airplanes and helicopters in product liability claims. As a panel attorney for the Legal Services Plan of the Aircraft Owners and Pilots Association, Darrell has advised, counseled, and defended dozens of pilots, mechanics, and other certificate holders in FAA and NTSB enforcement proceedings.

Darrell often represents law firms and attorneys, accountants and other service professionals in professional liability claims and other types of complex litigation. He has served as lead counsel in cases pursuing construction design and workmanship liability claims.

Darrell represents creditors in all phases of bankruptcy and complex collection litigation.

In the criminal arena, Darrell has handled dozens of high-profile matters, including trying the first case ever brought to trial under the Economic Espionage Act of 1996. He has represented and negotiated plea and immunity agreements for numerous clients, and is intimately familiar with the Federal Sentencing Guidelines and the forfeiture laws of Ohio. He has successfully defeated various asset-forfeiture claims and advised clients on criminal restitution orders. He has also represented non-target witnesses in testimony before grand jury and in responding to subpoenas for documents and electronic files.

Prior to joining Walter | Haverfield, Darrell practiced in New Orleans, Louisiana, where he served as a fellow in the nationally-recognized Institute of Politics. He also served as a judicial clerk to Judge Steven R. Plotkin of the Louisiana Fourth Circuit Court of Appeals. In his spare time, Darrell volunteers for Angel Flight, donating his time and airplane to fly persons in need of medical attention to destinations throughout the Midwest.
