Education
Vennerberg earned a Bachelor of Science degree in Psychology from Oklahoma State University (OSU) in 1976. During his tenure at OSU, Vennerberg was affiliated with the Delta Tau Delta fraternity and held leadership positions, including President of the Blue Key National Honor Society, the Student Union Activities Board, and the Interfraternity Council. In the year of his graduation, he was recognized as one of the Top 10 Seniors for the College of Arts & Sciences and was acknowledged in the Redskin Yearbook Congratulate, an accolade reserved for OSU’s top twelve graduating seniors.
Career
Following his graduation from Oklahoma State University in 1976, Mr. Vennerberg held the position of Senior Aide and Travel Coordinator for Bob Kamm’s U.S. Senate campaign in Oklahoma. Subsequently, Vennerberg returned to graduate studies, which he discontinued in March 1979 upon receiving an offer of employment from Texaco Inc. to participate in a land management training program. This marked the commencement of his accomplished career within the oil and gas industry. He remained with Texaco for five and a half years, after which he accepted a position with Cotton Petroleum Corporation, an independent oil and gas producer based in Tulsa. Two years later, Vennerberg departed Cotton to join a small independent firm in Tulsa for eight months. Subsequently, he was recruited by an executive search consultant seeking an experienced oil and gas professional, leading to his relocation to Fort Worth, Texas, in 1987 to help establish Cross Timbers, later known as XTO Energy.

Vennerberg served as a senior officer and then president and director of XTO Energy Inc., a publicly traded entity on the NYSE, until its acquisition by ExxonMobil in June 2010, a merger he played an instrumental role in negotiating. The New York Times characterized this transaction as “one of the most substantial energy mergers in history.” This $41 billion stock sale resulted in Exxon acquiring the equivalent of approximately 45 trillion cubic feet of natural gas assets across the United States.
He dedicated 23 years to XTO, which, prior to the merger, held the position of the largest domestic natural gas producer in the nation, employing over 2,200 individuals. During his tenure, his responsibilities included oversight of contract negotiations, regulatory relations, acquisition and divestment strategies, land management, gas marketing, property management, human resources, and Board of Director relations.
In 2012 Vennerberg became a founding member and partial owner of Fort Worth-based Morning Star Partners and Morning Star Oil & Gas. Morning Star subsequently became TXO Energy Partners (TXO).
Vennerberg has held directorial positions with several organizations, namely the New Mexico Oil & Gas Association, the Western Energy Alliance, the Fort Worth Chamber of Commerce, the Oklahoma Energy Resources Board, and the Oklahoma Independent Petroleum Association.
Additionally, at one time he held a minority ownership stake in the Texas Rangers baseball club.
