Jenner & Block


We are Jenner & Block’s first and largest office — the birthplace and center from which the firm has built its reputation and culture.  We first opened our doors in 1914 as Newman, Poppenhusen & Stern, a three-person firm located in downtown Chicago in a building that was erected soon after the great Chicago fire of 1871.  Today, Jenner & Block is one of the largest law firms in Chicago.  Approximately 330 of the firm’s attorneys are based in our 1.1-million-square-foot office at 353 N. Clark, in a Class A, LEED-certified office tower with sweeping views of Lake Michigan and the Chicago skyline.

Chicago office lawyers are involved in high-profile litigation and substantial transactions. The Chicago office made headlines in the latter part of the 2000s when we represented the Examiner in the Lehman Brothers Holdings bankruptcy and General Motors in its blockbuster IPO. We have entered our second century of business handling high-stakes, mission-critical litigation for Fortune 100 companies and other large organizations, delivering unmatched strength in all areas of dispute resolution. Chambers USA has ranked 10 of our Chicago-based practices as among the best in the United States. The American Lawyer, The National Law Journal, The Wall Street Journal and Financial Times have also recognized our practices and partners. Jenner & Block’s enduring commitment to pro bono and public service began in Chicago.  Today, our Chicago lawyers are among the city’s consistently most dedicated providers of pro bono legal services. They also serve as leaders in the organized bar and in a wide array of other professional and charitable organizations.

Our Chicago office attracts high-quality associates, many of whom were editors of their law school journals and have clerked for federal and state trial and appellate judges across the country.  Because so many of our national practices are headquartered in our Chicago office, associates have extensive opportunities to gain experience in different areas and participate in challenging cases and deals. We also attract high-level lateral partners and were pleased recently to welcome one of the city’s most well-regarded M&A attorneys and a former Assistant United States Attorney to our team.

Though it is our largest office, Chicago’s atmosphere is collegial and teamwork-focused, with a high degree of internal cooperation among the various practices.  This approach is an integral part of our culture and a cornerstone of our success in all of our offices today.
