In a burst of hiring activity, several major law firms have named new chief marketing officers in recent weeks. While CMO hires and departures are constant in Big Law, observers point to an unusual level of turnover.

In just the last two months, Hogan Lovells; Paul, Weiss, Rifkind, Wharton & Garrison; Stroock Stroock & Lavan; and Akerman have all added new chief marketing officers, after chief marketers left Fried, Frank, Harris, Shriver & Jacobson; Shearman & Sterling; Fox Rothschild; and Williams & Connolly.
