Katie Peterson-Hesketh

Raised in Rockford, Illinois, Katie developed an interest in art at a young age — but it wasn’t until her first international trip to Paris, standing in front of the Palais Garnier, that she was inspired to study architecture. After receiving her Bachelor of Science in Architecture from Ball State University, Katie moved to Los Angeles to pursue her career and later received her Master of Architecture at UCLA.

Since joining TBA in 2012, Katie has brought expertise in both modern and historic residential architecture, starting as a Design Associate and now a Principal Architect. While leading projects, she concentrates on translating design intent into the built environment, ensuring that every decision reinforces the integrity of the project and the client’s vision. Knowledgeable about the Mills Act Historical Property Contract Program, she also helps homeowners navigate opportunities for preservation and restoration. Outside of TBA, Katie enjoys renovating her eclectic 1930s home with her husband.
