About Our Team

At GIS MidStream, our management team brings extensive industry experience to the table.

More than providing innovative solutions, we also bring the passion and care to look at every decision and opportunity through the lens of long-term, shared-value creation. We work hard to demonstrate operational excellence by incorporating energy conservation, social and environmental awareness. Our solutions strive to bridge the gap between industry and community, both internally and externally. Most importantly, we’re here to address this growing need in the American energy infrastructure, including natural gas and natural gas liquids (NGL) processing and heavy oil upgrading and transportation—through sustainable responses that address today’s midstream challenges. Collectively, our Leadership Team has demonstrated industry success, managing and sponsoring capital projects ranging from $100 to over $600 million. Meet our team below.
