Vinson & Elkins has named a new chief financial officer and Haynes and Boone hired a new chief marketing officer, as the Texas-founded Am Law 100 firms, like others in Big Law, focus on C-suite staffing.

At Vinson & Elkins, Charyn Ullrick moved into the CFO role in September, after joining the firm in January as global director of finance and accounting. She worked in senior management roles at a number of firms over the last 20 years, most recently as Dallas-based director of finance for Foley & Lardner.
