Zack co-founded Oliva Gibbs in 2013 and currently serves as Co-Owner. His primary role at the firm is strategic planning. The decision to start the firm was driven by Zack’s desire to create a great company focused on the energy industry, with a passionate team of colleagues who share the goal of doing things better.

Zack has primarily worked with upstream operators and oilfield service companies on the drafting and negotiation of contracts, complex title issues, and the purchase and sale of assets across New Mexico, Ohio, and Texas. Additionally, entrepreneurs in the energy industry seek his assistance with business partnership issues such as negotiating complicated partnership dissolutions or exits, advising on key business milestones, and advising on issues between business partners. A lifelong student of investing, he offers a unique perspective to leadership teams and owners through the intersection of his legal background and his experience as a professional investor and founder of Oliva Partners Management LLC, a long-only value investment fund.

Outside the firm, Zack is actively involved in shaping the energy and legal sectors. He serves on the Advisory Board for the Institute for Energy Law and mentors emerging leaders through the Entrepreneurs’ Organization (EO), contributing to meaningful industry discussions and policy development. He enjoys spending time with his family, reading, traveling, and practicing jiu-jitsu.
