Peggy is a recognized expert in developing customized, innovative solutions for meeting security standards that elegantly balance risk and vulnerability with architectural excellence, functionality, constructability and cost.

Peggy Van Eepoel established and currently oversees the Protective Design & Security practice in the Washington, D.C. office. During her 15-year plus career, Peggy has been involved in the design and structural hardening of more than 100 buildings, including facilities for the U.S. Department of State, General Services Administration, Department of Defense and Veterans Administration. Her diverse portfolio also includes master-planned facilities, office buildings, educational facilities, laboratories, military housing, courthouses, museums and hospitals. Peggy joined Thornton Tomasetti in 2015 through its merger with Weidlinger Associates, for which she served as an associate principal.

Integrated Solutions
Working in close collaboration with clients and other members of the design team, Peggy develops appropriate and practical protective-design approaches for new construction, renovations and historic restorations. Her expertise includes the identification of applicable security standards, site security planning and determination of the blast-loading environment, dynamic analysis of building structure and envelope elements, and progressive-collapse analysis.

Professional Contributions
Peggy has authored numerous papers and articles and has contributed to various technical manuals and guidebooks. She is currently serving as co-editor of an update to the American Society of Civil Engineers’ Structural Design for Physical Security, which will be a state-of-the-practice manual for the design of structures for blast effects.

Outside of Work
Peggy is a fitness enthusiast, and is into cycling, spinning, running and hiking. She enjoys traveling around the world and has recently set her sights on exploring the United States with her husband and two young daughters. Peggy, who in another life might have been a historic preservationist, likes to visit architecturally significant sites wherever she goes. Closer to home, she is involved with the youth group at her church and serves as co-leader of her daughter’s Girl Scouts troop.
