Lloyd Landreth began his environmental career as a fisheries biologist in the central and northwestern United States.  During his tenure with the U.S. Fish and Wildlife Service in Washington, Lloyd had the opportunity to observe how the law and fisheries science merged through the landmark Boldt decision. With an interim stint as an air quality regulator, Lloyd transitioned from the natural and environmental science field to the practice of law by attending the University of Colorado School of Law.  Since graduating from law school in 1986, Lloyd has been fortunate to work in a variety of public and private sector positions and associate with some of the preeminent law firms and environmental lawyers in the nation.

Lloyd’s legal career led him to the regional law firm of Gardere Wynne Sewell, where he worked as a Partner until the summer of 2002, when a change in firm practice group emphasis led to the closing of Gardere’s Tulsa office. With a group of supportive and outstanding clients and staff, Lloyd made the decision to manage his own law practice, and founded the Landreth Law Firm in September of 2002.
