J. Keyes Williamson, Principal Landscape Architect

As the lead principal at WLA Studio, Keyes manages preservation and construction projects that incorporate both sustainable design principles and the Secretary of the Interior’s Standards for the Rehabilitation of Historic Properties. Prior to joining TJC, Keyes spent a decade as a gardener and administrator at historic sites, including Monticello in Charlottesville, VA and Old Salem in Winston-Salem, NC.  Keyes also served as the Executive Director of the Knoxville Botanical Garden and Arboretum.  This experience working at public sites informs Keyes’ design approach that facilitates the interaction between people and the landscape. A native of Tallahassee, Florida, Keyes received his B.A. from the University of the South (Sewanee), an M.A. from Florida State University, and his M.L.A from the University of Georgia. In addition to being a doting father, Keyes continues in his quest to hybridize the perfectly fragrant and disease-free gardenia.
