We started practicing in the mid 2000s under the name JRS Engineering LLC, and have since expanded to work on projects big and small both across the U.S. and internationally. While we're currently based primarily on the West Coast of North America (including Canada), our experience has taken us to the East Coast U.S., Mexico, and China, among other regions.
