Zachary A. Madonia

Senior Attorney

Zac Madonia’s practice focuses on the representation of public and private companies, and their officers and directors, in all stages of complex litigation. Some of Zac’s recent representative matters include federal securities class actions, shareholder derivative suits, state and federal antitrust litigation, intellectual property disputes, business torts, and breaches of contract. These cases have involved complex legal issues related to class certification, market definition, antitrust injury, loss causation, public disclosures, breach of fiduciary duty, patent damages, and the legality of a variety of business practices.

Zac has a wide range of litigation experience in both federal and state courts, including examining witnesses, taking and defending depositions, working with expert and fact witnesses, writing and arguing dispositive motions, appellate briefs and oppositions to class certification, and managing significant electronic discovery. He is also actively involved in pro bono matters.

Zac joined Bradley after more than six years of litigation experience at Sidley Austin LLP in Chicago, where he focused his practice on antitrust, securities, and shareholder litigation.
