William E. Hoese

“We provide legal services to accomplish client goals, obtain compensation for those injured, or change conduct that harms people. This work benefits our clients and society at large and provides powerful motivation to get out of bed each day with a sense of purpose to resume the fight.”


William A. Hoese’s practice focuses on suing to stop price-fixing, securities fraud, consumer fraud, and sales of defective or dangerous products, and to recover damages for those harmed by such conduct. He has been pursuing claims on behalf of injured parties for over 30 years.

Mr. Hoese believes the most important thing lawyers can do is understand the facts, what the clients’ needs are, and what they want to accomplish. He considers problems from different angles to quickly and accurately appreciate how the facts of a particular case fit into the law, and if they do not, to consider and propose an alternative course of action. He also believes that good judgment is critical, as is a reputation for integrity, legal expertise, and working well with other lawyers and the courts.

Prior to joining Kohn Swift, Mr. Hoese served as a senior trial counsel in the enforcement division at the Securities and Exchange Commission’s Philadelphia regional office, where he investigated and brought appropriate actions for violations of the securities law.

Mr. Hoese received his Juris Doctor degree, magna cum laude, from the Syracuse University College of Law in 1984. He was inducted into the Order of the Coif and the Justinian Honor Society. He received a B.A. degree with honors in political science from The College of Wooster in 1980. He is a member of Phi Beta Kappa.

Kohn Swift brought a class action lawsuit by and on behalf of persons with hemophilia who were infected with the human immunodeficiency virus (HIV) from their use of contaminated factor concentrates, which were products made from human blood plasma to control internal bleeding.

The persons with hemophilia sued factor concentrate manufacturers, alleging that: 1) manufacturers’ testing of plasma used to make factor concentrates for the presence of HIV or other viruses was inadequate; 2) the manufacturers’ screening of high-risk plasma donors was faulty; and 3) the manufacturers failed to provide necessary warnings to hemophiliacs and their physicians of the dangers of HIV transmission through use of factor concentrates. The case was hard fought, with many ups and downs, and was ultimately successful.


Kohn Swift has served as co-lead counsel since 2012 in 28 direct purchaser cases alleging price fixing and bid rigging for numerous automotive parts. The criminal investigation has been described as the largest in Department of Justice history. To date, Kohn Swift and its co-counsel have obtained over $359.5 million in recoveries.



Direct purchasers of cheese and butter alleged that large dairy cooperatives and their trade association agreed to reduce the number of dairy cows, and thus the supply of milk, to drive up the price of cheese and butter, which, due to how wholesale milk prices are set, would increase milk prices. The case involved a number of complicated issues, such as whether the Capper-Volstead Act shielded the cooperatives’ conduct, and the implications of Federal Milk Marketing Orders. Lawyers from Kohn Swift worked on multiple aspects of the case, including briefing, depositions, arguing motions, class certification, and trial preparation, and with the class and damages experts. The case settled on the eve of trial for $220 million.



In this class action, the court appointed Kohn Swift sole lead counsel in the first-of-its-kind sealed bid “auction” procedure in an antitrust case, concluding: “Although a small firm by today’s megafirm standards, it has amply demonstrated its ability to handle major litigation.” The case settled for more than $50 million.
