Shannon M. Kasley has joined McGuireWoods’ global litigation practice as a partner in Washington, D.C., bringing 25 years of experience representing multinational companies in commercial and civil litigation and appeals, including clients in the oil and gas industry.

Kasley represents oil and gas companies in multiparty and multidistrict litigation, including commercial disputes; fraud claims; sensitive environmental, social and governance (ESG) issues; antitrust matters; product liability, mass tort and environmental cases; and challenges to regulatory and administrative actions. He has counseled clients in all phases of litigation, appearing before trial and appellate courts, administrative bodies and arbitration panels throughout the country.

In addition, Kasley has advised corporate clients and individuals in civil and criminal investigations conducted by the Department of Justice, the Securities and Exchange Commission, the Internal Revenue Service, the Office of the Comptroller of the Currency, the FBI, U.S. Army Criminal Investigation Command and numerous state attorneys general. He joins McGuireWoods from King & Spalding.

“Shannon is an accomplished trial lawyer with a long track record of helping national and international companies overcome litigation challenges and manage risk,” said Dion Hayes, deputy managing partner of McGuireWoods’ litigation practice. “He is a perfect fit for our practice.”

“Shannon has a national reputation as a go-to lawyer for oil and gas companies and other corporate clients in high-stakes litigation matters,” said Jonathan Blank, chair of McGuireWoods’ Business & Securities Litigation Department. “His skill and insight will have immense benefits for the firm and our clients.”

Kasley’s arrival enhances the firm’s formidable litigation bench in D.C. Notable additions in 2022 include Brian Baltz, a former SEC attorney who joined the securities litigation and enforcement team; Ben O’Neil, a former federal prosecutor with experience in international anti-corruption matters; and Jeff Ehrlich, former deputy enforcement director at the Consumer Financial Protection Bureau. 

“Shannon is an important addition who enhances our considerable litigation capabilities, and we are delighted to welcome him,” said Todd Mullins, managing partner of the D.C. office.

McGuireWoods’ commercial litigation team defends clients’ interests in domestic and cross-border matters in courtrooms and tribunals around the world. The firm earned national Tier 1 rankings for commercial, construction and environmental litigation in the 2022 edition of U.S. News-Best Lawyers’ “Best Law Firms.”

“I am very familiar with the McGuireWoods team and the firm’s reputation as a litigation powerhouse,” Kasley said. “I am excited for the opportunity to collaborate with world-class lawyers and to get to work for our clients.”
