Peter Wilson Jr. recalls being skeptical about big law firm culture when he became an associate at Day, Berry & Howard nine years ago. His concerns mirrored those of many associates: He was worried about getting quality work and advancing into leadership positions.

But as a young black attorney, he also was concerned about who his mentors would be and whether he would be given the opportunity to become successful in the firm. Then a year or two later, he was asked to join the firm’s hiring and diversity committees, and he got a true feel for the firm’s attitude toward diversity.
