I am a licensed structural engineer with over 16 years of experience designing high-profile civic structures, museums and performing arts centers throughout the United States. Prior to joining StructureCraft as Structural Engineering Director in May of 2021, I was a Principal at MKA in Seattle, where I also led MKA’s Timber Technical Specialty Team.
I attended Lawrence University in Wisconsin and Washington University in St. Louis where I obtained undergraduate degrees in Physics and Civil Engineering. While at Washington University in St. Louis, I received my master’s degree in Structural Engineering. Shortly after graduation and before moving to Seattle, I won the 2004 Skidmore, Owings and Merrill Structural Engineering Traveling Fellowship, where I toured Europe to study structures inspired by natural forms for his thesis “Nature as Inspiration: Tools for Structural Art”.
My portfolio includes many high-profile structures, including:
- Hines' T3 Projects
- MoMA in San Francisco
- The Perelman Center in New York
- Nordic Museum in Seattle
- Lincoln Park Zoo Timber Pavilion
