He helped lead the company’s design of governance policies and processes and has significant international experience with governance, regulators, and capital markets matters. Sullivan also works with the Board and CEO on executive compensation planning as well as recruitment, vetting, and on-boarding of new independent Board members and has significant experience with negotiating complex and bespoke financial arrangements, including asset backed securitizations. He has served as co-lead on multiple public equity raises and on significant acquisitions and divestures totaling more than $1.5 billion. In his role, Sullivan also assists in oversight of interactions with state, federal, and international regulators and officials.
Prior to joining Diversified, Sullivan worked with Greylock Energy, an ArcLight Capital Partners portfolio company, and its predecessor as executive vice president and general counsel. Prior to his tenure at Greylock, he worked as counsel for EQT Corporation as well as with a private law firm. He is a member of the leadership and Board of Directors of several commerce, legal, and industry groups.
