SIM Architects (SIM) was founded in 1987 with a vision for a new kind of architectural practice – a company that combined the art of innovative design with the efficiency of meticulous project management. Thanks to our founders’ collective talent and the support of a dedicated team, the firm has earned a reputation for unsurpassed architectural innovation, business integrity, and client satisfaction. SIM’s unique process adds an element of emotion to the disciplined pursuit of quality — this enables the team to arrange the combinations and interrelations of scale, proportion, texture, color and light into a structure that is functionally efficient, visually appealing, and emotionally awe-inspiring.

While collaborating on a project in the Spring of 2014, SIM and PBK Architects (PBK) immediately noticed a symbiotic approach to project delivery that prioritizes customer service through strong client relationships and professional integrity. Since that time, the team has completed numerous commissions from Los Angeles to Sacramento, and throughout the Central Valley. SIM and PBK created a formal alliance in Spring 2017. Together, SIM-PBK combines small business attention and responsiveness with big business experience, expertise, and an industry-leading depth of resources.
