Sidley’s leadership on behalf of clients hasn't gone unnoticed. Sidley received 47 first-tier national rankings, more than any U.S. law firm, in the 2019 U.S. News – Best Lawyers® “Best Law Firms” survey. This marks the second year in a row, and the eighth time since the survey’s inception, that Sidley has collected the most first-tier national rankings..
Beyond its deep reserve of talent, Sidley’s ingrained culture of teamwork is evident in its interactions with clients. BTI, a Boston-based research and consulting firm, has named Sidley as one of only three firms to place on The BTI Client Service 30 list for 14 consecutive years. Sidley has been recognized every year since the inception of those rankings in 2001.
Sidley has been widely recognized for its pro bono and diversity programs. Working Mother named Sidley one of the 2018 “Best Law Firms for Women,” and the firm received a perfect score of 100 percent on the Human Rights Campaign’s Corporate Equality Index (CEI) report 2008–2019.
