Colleen Powers represents clients in a wide range of matters including antitrust litigation, securities litigation, insurance coverage, bankruptcy matters, Foreign Corrupt Practices Act investigations, class actions, contract/commercial disputes, and matters before the US International Trade Commission (ITC). Colleen has broad litigation experience in discovery matters, preparing for depositions (including fact witnesses and experts), drafting dispositive motions, and preparing for trial. 

Colleen has extensive experience representing clients in complex antitrust matters. Colleen was a key member of the team that helped secure a victory for C. R. Bard, Inc. in a Sherman Act Section 1 tying case brought by a competing provider of medical devices. Just a few months prior to the Bard trial, Colleen helped US Airways secure a victory in a multi-week jury trial in which the jury found Sabre liable for violating the Sherman Act, Section 2. Additionally, Colleen played a lead role in coordinating and analyzing discovery in an ongoing multi-bank antitrust class action.

In her pro bono practice, Colleen devotes time advocating for voting rights and indigent clients, including participating in a week-long evidentiary hearing to overturn a death sentence which the state of Texas ultimately determined was unconstitutional, securing a favorable settlement in a civil rights matter, and drafting a Second Circuit brief challenging the denial of immigration relief for a client seeking asylum.
