Managing Principal
Steve offers more than two decades of experience in K–12 school design for districts across Western WA. His portfolio includes both elementary and secondary schools, projects where he tackled technically complex challenges, optimized project budgets, and strengthened both functionality and the character of the learning environment.
As co-leader of TCF Architecture’s Educational Studio, Steve helps guide the firm’s delivery, documentation, and quality control processes. His attention to detail, clear communication, and steady leadership support thorough, well-coordinated project outcomes. A lifelong connection to the outdoors shapes how Steve approaches design. Time spent skiing, mountain biking, and exploring informs a practical understanding of natural forces and conditions. That firsthand perspective carries into his work, where considerations like seismic performance and tsunami resilience are approached with both technical rigor and lived awareness.
