Previously, as CEO of Deloitte, Engelbert was first woman ever to lead a Big Four professional services firm in the U.S. where she oversaw one of the largest professional services organizations with more than 100,000 professionals. Over the course of her tenure, she drove a large transformation across the business by moving the firm towards emerging technologies such as AI, blockchain, robotics and cloud, including securing ecosystem partnerships with large technology companies, and executing digital acquisitions. Revenues grew more than 30 percent under Engelbert, and her people-first agenda included implementing a holistic well-being culture through programs like Deloitte’s 16-week family leave policy.
