Company Leadership

Darby W. Hittle

Darby Hittle is a Licensed Environmental Professional (LEP) with more than 25 years experience providing environmental site assessment, remediation design and oversight, and regulatory compliance assistance to a wide range of private and federal clients throughout North America.  Darby is a 1995 graduate of Bloomsburg University of Pennsylvania, where he earned a B.S. in Geology. 


Darby is Veteran of the United States Air Force, where he served as a fire protection specialist assigned to Air Force One from 1988 to 1990, and as a civil engineer/fire protection specialist in Panama from 1986 to 1988.  

When he's not helping one of Thunderbird's many clients with environmental issues, Darby can likely be found on a cold water stream casting a trout fly, playing guitar, or planning the next western fishing or hunting adventure.  Growing up in the small farming community of Benton, Pennsylvania, Darby developed an early understanding of the need for responsible use of our natural resources.  Thunderbird Environmental is named after a neighbor's dairy farm, where Darby spent much of his boyhood life exploring the local streams, fields, and forests and discovering the small wonders that exist within nature.
