Sims surprised many with the news that she’ll transition to her next chapter after more than 13 years as a key part of Discovery and now WBD’s leadership team. Given the key role she plays in virtually every aspect of the business, you can bet many were relieved she agreed to stay on for a while as the company searches for a new legal chief. Sims gets kudos for the role she played in the acquisitions of Warner Media and Scripps Networks as well as complex negotiations, such as those with labor unions. She also led WBD’s legal team in partnering with Street Law for a program designed to expose young students in diverse communities to professional opportunities in the legal profession.
