We forge partnerships with our clients based on our uniquely flexible and entrepreneurial culture. Knowing the law is not enough: we understand our clients’ business objectives and address their legal needs in a manner that is consistent with the “big picture.” Our clients see us as trusted advisors and we demonstrate our value every day in the successful results we earn.

Katten is deeply committed to diversity and we are frequently honored for our diversity program. We value the talents and perspectives of our diverse teams of attorneys, building stronger solutions for our clients and a better workplace for everyone.

Through our pro bono program, our attorneys and other legal professionals give their time, resources and talent to serve individuals and organizations in need, to engage in important national litigation and to partner with local legal service providers to ensure access to the justice system. We understand that by enriching the lives of those around us, we grow as a firm and as individuals. With our Katten Cares program, we have invested millions of dollars and thousands of hours in making a positive impact on our communities through sponsorship of local community service programs and the charitable activities of our attorneys and staff.

Katten is intensely focused on ensuring that we offer the best services to our clients and, in turn, sharing our support with community organizations.
