Troutman Pepper Locke LLP

Troutman Pepper Locke LLP‘s practice is anchored in contentious work, with a particular focus on monopolization claims and large-scale class action disputes. The group is jointly led by Barbara Sicalides, whose Philadelphia-based practice spans transactional advice through to the defense of antitrust investigations and follow-on litigation. Brad Weber co-leads the firm’s practice from the Dallas office, while Daniel Anziska in New York brings regulatory and competition insight across a range of heavily regulated sectors. The team benefits from a litigation core, with Jeremy Heep handling both domestic and cross-border competition disputes, operating in Philadelphia. The practice is further strengthened by Robin Sumner, also in Philadelphia, whose experience in biopharma and healthcare-related antitrust litigation adds valuable sector-specific depth.
