Britt Whitesell Biles, a litigation partner at Stein Mitchell Beato & Missner LLP, has substantial experience in complex civil litigation and regulatory matters, having successfully litigated cases in state and federal courts and before administrative tribunals, arbitrators, and mediators.  As a former senior litigation official with the Securities and Exchange Commission (“SEC”), Ms. Biles brings unique experience and insight to the individuals and businesses she represents in a variety of industries including: healthcare, pharmaceutical, manufacturing, defense, energy, telecommunications, and financial services.

Ms. Biles has served as counsel on a diverse array of cases, including, class actions and mass torts; commercial contract disputes; Congressional investigations; cases involving cybersecurity and privacy breaches, environmental contamination cases; private securities litigation; product liability cases; and regulatory investigations and enforcement proceedings brought by the SEC, the Federal Trade Commission, the Federal Deposit Insurance Corporation, and various state attorneys general.  In addition, she has developed a reputation for her expertise in managing highly sensitive corporate crisis issues to mitigate risk and exposure for clients facing significant liability, existential regulatory threats, and negative media attention.   

Ms. Biles joined Stein Mitchell from the SEC, where she served as Assistant Chief Litigation Counsel in the Division of Enforcement. At the SEC, Ms. Biles investigated and litigated notable securities enforcement actions involving issues such as insider trading, accounting and disclosure fraud, unregistered securities offerings, market abuses, and the Foreign Corrupt Practices Act, as well as varied misconduct by broker-dealers, investment advisors, and gatekeepers.  She also served on task forces and advisory groups concerning pyramid schemes and digital currency.      

Ms. Biles led the litigation in the SEC’s groundbreaking law firm hacking case in which Chinese nationals were charged with trading on the basis of material nonpublic information that was stolen when the computer networks of two prominent international law firms were hacked.  In recognition of her work on that case, Ms. Biles received the Chairman’s Award for Excellence in 2017. 

For her roles in other significant enforcement actions, Ms. Biles was a two-time recipient of the Division of Enforcement Director’s Award. She was also named by Super Lawyers as a rising star in litigation in 2014.
