Thomas M. Weber

Tom’s practice focuses on energy, environmental and water law and he represents clients in state and federal courts and before the Railroad Commission, Texas Commission on Environmental Quality, the Texas General Land Office, and the U.S. Environmental Protection Agency. His clients range from oil and gas operators and power companies to landowners and local and international environmental groups. Tom spearheaded the expansion of the firm’s environmental and water law practices with an emphasis on the overlap between oil and gas, environmental, and water law. Because of his unique engineering, policy, and legal background, Tom enjoys the challenge of technically complex energy and environmental cases. Notably, Tom was lead counsel in the successful fight against coal-plant expansion in Texas.

Prior to attending law school, Tom put his engineering degree to work with Platt, Sparks & Associates, an Austin-based petroleum engineering consulting firm, while simultaneously obtaining a graduate degree at the University of Texas, LBJ School of Public Affairs, where he focused on energy and environmental policy. Tom took a leave of absence from the firm and served as Interim Deputy Chief of Staff & District Director to a serving member of the U.S. House of Representatives. Tom has written and spoken extensively on carbon capture and sequestration and served on the Planning Committee of the University of Texas Conference on Carbon and Climate Change. Tom has served on the board of the Texas League of Conservation Voters since 2009.

Tom is an avid outdoorsman who is happiest when hiking, camping, and kayaking with his wife and two teenagers. He also enjoys traveling, soccer and is a huge University of Texas basketball fan. He is also a founder of the Dripping Springs Ranch Wildlife Management Cooperative and former board member.
