Our Team


The EnCap Flatrock Midstream management team is led by Managing Partners and Founders Bill Waldrip and Billy Lemmons and Founder Dennis Jaggi, who have worked together for the majority of the past 30 years in the midstream sector of the oil and gas industry. With more than a century of combined midstream experience, they have been directly involved in approximately $17 billion in midstream transactions and investments. In their previous advisory practice, Flatrock Energy Advisors, they were widely regarded as leading experts in the North American midstream market and provided evaluation, due diligence and transaction advisory services, as well as asset enhancement services on expansion, efficiency and supply matters to more than 125 midstream entities, both public and private. Flatrock was engaged in nearly all of the key producing areas in North America. These engagements included more than 35 successful acquisition and greenfield development closings totaling more than $2 billion. Both Mr. Jaggi and Mr. Waldrip have served as chief operating officers and as division heads of large midstream companies with full operations, profit and loss, and capital investment responsibilities. Mr. Lemmons has significant experience originating, structuring, negotiating and overseeing energy investments. They are joined by Managing Partners David Kurtz, Greg King, Sam Pitts and Morriss Hurt.
