David H. Thomason

Member, Evansville

A Senior Member of Stoll Keenon Ogden’s Evansville office, David has been with the firm since 1998. He belongs to the Mineral & Environmental Law and Government Relations practice groups.  

David has served the coal, oil and gas industries for most of his career, in many capacities. He is licensed to practice law in six states to ensure he can handle the full scope of a client’s interests, “since minerals do not respect state borders.” At the early part of his career, he spent more than 10 years working for the Kentucky Oil and Gas Association as their chief lobbyist.

Mineral & Environmental Law: David has long held the distinction of being one of the nation’s leading attorneys in this continually changing specialty area. He has successfully handled acquisitions involving coal, gas and oil ventures worth hundreds of millions and even billions of dollars. He recently led a real estate due diligence team representing the purchaser in what has been described as the largest mineral swap in the history of the United States.

Government Relations: As a former Henderson County Attorney (Kentucky) and Speaker Pro Tempore of the Kentucky House of Representatives, David is well acquainted with the workings of the government and the intricacies of regulation. This knowledge makes him an invaluable liaison between his clients and government entities.
