Philip Thomason


Phil ThomasonPhil Thomason is principal of one of the oldest preservation firms in the country. His breadth of experience, passion for livable spaces and mediation skills all come into play as he helps clients identify and articulate the value of their historic resources and communicate that value to the community.

During recent decades, Thomason’s work and his firm have reflected the evolution of historic preservation in the U.S. Focusing first on National Register nominations and cultural resource surveys, he soon branched out into preservation plans, design guidelines for towns and communities, and environmental assessments. Initially focused on the Southeast, his work expanded throughout the country. Along the way, he developed a unique expertise in military architecture.

A native of Georgia and Kentucky, he grew up in historic neighborhoods and experienced their intrinsic value. Upon completion of his B.A., he pursued a career in public radio before returning to school to earn an M.A. in historic preservation in 1978. He worked as a preservation planner with Building Conservation Technology, Inc. until 1982, when he founded Thomason and Associates.

Her interest in agriculture- and equine-related history has been the basis for projects from her Master’s thesis, “Horse Race: Class and Gender: American Cultural Identity through Horse Racing” to the Thomason and Associates’ National Register nomination for Thompson Creek Rural Historic District and associated Bedford County, Tennessee, agricultural context.

Andra presented research at the Equine History Collective’s inaugural conference at the Will K. Kellogg Arabian Horse Library at the Cal Poly University campus in Pomona, CA. Her paper addressed the theme, “Why Equine History Matters,” following the story of a World War II prize-of-war stallion from pre-war Poland to modern American culture. Her research includes a recent trip to Poland for development of historical, cultural, and architectural contexts, as well as for personal family history. Andra is also the author of Tennessee’s Arabian Horseracing Heritage, published as part of Arcadia Publishing’s “Images of America” series.
