Thomas M. Cooley Law School

Thomas M. Cooley Law School (commonly referred to as Cooley Law School) is a private law school in Lansing, Michigan, with an additional campus in Riverview, Florida. It was established in 1972 by a group of lawyers and judges led by Thomas E. Brennan, a former Chief Justice of the Michigan Supreme Court.

The school is named in honor of Thomas McIntyre Cooley, a prominent 19th-century jurist who also served as Chief Justice of the Michigan Supreme Court. At its peak in 2010, Cooley had over 3,900 students and was the largest U.S. law school by enrollment.
