How We Started

Smithson Engineering is a family business that started with a few side jobs for Architects while Tyler worked his day job at an engineering software firm. The business went full time in 2000 and sustained Tyler & Cyndi as they raised 6 wonderful children amidst their own remodels and construction projects in the San Bernardino Mountains of Southern California.

Where we are Now

With their nest empty, they moved to the beach. Now they are focused on 6 grandchildren while continuing to help clients through the challenges of getting from an early design concept to a cost efficient construction permit.
