Allison Reimann

Allison helps clients decipher complex legal and factual puzzles with the goal of identifying effective and efficient strategies for positive outcomes. Allison’s diverse practice focuses on civil litigation, government investigations and antitrust in a broad complement of industries with a particular focus on health care.

A substantial portion of Allison’s practice is devoted to civil litigation and government investigations in the health care industry. Allison has represented a range of health care clients, including hospitals, health systems, health insurers, pharmaceutical and medical device manufacturers, pharmaceutical wholesalers, clinical laboratories, and other providers, in matters including:

  • Individual and class actions brought under federal and state antitrust laws for alleged agreements in restraint of trade and monopolization
  • Complex commercial litigation and employment disputes
  • Civil litigation under the False Claims Act and state equivalents
  • Responses to Civil Investigative Demands and grand jury subpoenas in connection with government investigations of alleged health care fraud

Allison also handles complex civil litigation and government investigations for non-health care clients, particularly in the areas of antitrust, deceptive trade practices, and contract disputes.

The balance of Allison’s practice is devoted to the area of antitrust. Allison has counseled clients on a range of antitrust issues including collaborations between competitors and advertising and pricing issues. She also is experienced in pre-merger antitrust investigations, including second requests under the Hart-Scott-Rodino Act.

Prior to joining Godfrey & Kahn, Allison practiced health care litigation and antitrust litigation at Sidley Austin LLP in Chicago for six years. She also was a law clerk for the Honorable William C. Canby, Jr. of the Ninth Circuit Court of Appeals.

Before law school, Allison worked for five years as an environmental consultant in the area of regulatory compliance. She also backpacked across four continents for a year.
