About Jeffrey
Jeffrey Dorman combines legal training and formal economic study in a career that spans decades. He began his academic path at the University of Michigan, earning a B.A. in 1971. He then took a law degree at Case Western Reserve University School of Law, completing an LL.D. in antitrust in 1974. After law school he added graduate study at the University of Wisconsin–Madison, receiving an M.S. in industrial organization and econometrics in 1976. Those credentials give him an unusual mix of doctrinal and quantitative preparation.
His private practice career started in the late 1970s. In 1979 he became a partner at Sonnenschein Nath & Rosenthal, where he handled matters that required attention to both legal structure and business reality. He moved roles over the years, becoming a partner at Freeborn & Peters LLP in 2000. In 2011 he took an of counsel position with Voelker Litigation Group, a shift that allowed him to concentrate on specific litigation assignments and advisory work.
Dorman later joined Loftus & Eisenberg, Ltd, where he is listed as part of the firm’s practice. Throughout his career he has maintained a presence in Illinois courts and in the state’s legal community. His work has repeatedly brought together antitrust law and economic analysis. That combination appears in how he approaches damages questions, market-definition disputes, and other issues where legal rules intersect with market data.
He has handled complex commercial litigation that required an understanding of both legal theory and quantitative proof. His academic background in econometrics informs the way he reviews expert reports and evaluates the evidentiary needs of a case. Colleagues and opposing counsel have noted the steadiness of his courtroom presentations and his readiness to delve into technical material when a case demands it.
Across several firms and roles, Dorman has balanced direct litigation with advisory work. He has taken on matters that involve multi-party disputes and cases where economic models are a central feature of the proof. He remains admitted to practice in Illinois, and his professional path reflects sustained engagement with antitrust questions and commercial disputes. He is currently practicing at Loftus & Eisenberg, Ltd in Illinois, concentrating on antitrust and complex commercial litigation.
