Our Firm

Jenner & Block is defined by the exceptional results we produce, the values we share, the clients we serve and most importantly, our lawyers.  Jenner & Block lawyers consistently deliver excellence in the most complex and demanding legal matters, both litigation and transactions. They do not consider the practice of law a job, but rather a calling to serve clients, the profession and the community.  No matter what legal challenge is presented, our powerful combination of experience, professionalism and teamwork helps clients achieve their goals.

Founded in 1914, Jenner & Block is a law firm of international reach with more than 500 lawyers in six offices, including Chicago, London, Los Angeles, New York, San Francisco, and Washington, DC.  Our firm has been widely recognized for producing outstanding results in corporate transactions and securing significant litigation victories from the trial level through the United States Supreme Court.  Companies and individuals around the world trust Jenner & Block with their most sensitive and consequential matters.  Our clients range from the top ranks of the Fortune 500, large privately held corporations and financial services institutions to emerging companies, family-run businesses and individuals.

We have earned our reputation as a litigation powerhouse.  The 400 lawyers in our nationally recognized litigation department have won impressive victories in complex and challenging cases in a broad range of substantive areas of law and across a wide variety of industries, before federal, state and administrative courts and in arbitrations.  We have achieved landmark rulings on behalf of clients in matters before the United States Supreme Court — our appellate advocates have presented 21 oral arguments to the Court in the last 10 terms, and we also have an extensive amicus practice.

Lawyers in our transactional practices represent international and domestic clients in connection with mergers and acquisitions, joint ventures, strategic alliances and dispositions of businesses.  We also regularly advise clients regarding public and private securities offerings and financings and in areas such as real estate, tax, environmental, insurance, commercial law, technology, intellectual property, bankruptcy and reorganization, labor and employment, executive compensation, government contracts, health care and associations.

A commitment to public service is part of the DNA of our firm.  We are known for our long tradition of pro bono advocacy, as well as service to the bar and to our communities.  The American Lawyer has ranked Jenner & Block as the no. 1 pro bono firm in the United States 11 times, most recently in 2020.  Other accolades have come from The National Law Journal, which named the firm to its 2020 "Pro Bono Hot List."

Many organizations have recognized us for the pro bono work we do.  The US District Court for the Northern District of Illinois and the Chicago Chapter of the Federal Bar Association regularly honor the firm with their Award for Excellence in Pro Bono Service. The firm has received the prestigious Pro Bono Publico Award from the American Bar Association, the Pro Bono Institute’s John H. Pickering Award, the Public Interest Law Initiative's Pro Bono Initiative Award, the DC Bar’s Pro Bono Law Firm of the Year Award and numerous others.  In addition, many firm lawyers have received individual awards for their pro bono work.

Jenner & Block lawyers rise above the rest both in terms of their qualifications and their approach to practicing law. Several Jenner & Block lawyers currently serve as federal judges, building on a remarkable history of judicial service by member of the firm. One former partner served as the United States solicitor general.

We recruit our lawyers from top-tier law schools and prominent clerkships, and foster their growth and development with training, mentoring and casework.  We foster creativity in the practice of law, while also holding our lawyers to a rigorous set of performance standards.  Our culture combines entrepreneurism with an atmosphere of collegiality and teamwork.
