Building excellence for over 50 years

In 1959, Pacific Systems Interiors, Inc. (PSI) was founded as a subcontractor specializing in electrical and luminous ceiling systems.

With the goal of becoming a premier contractor in Southern California, in the 1970’s we began focusing our efforts on wall and ceilings systems. In order to better meet our clients’ needs, our capabilities grew to include demountable partitions, acoustical soundproofing, doors, frames & hardware, and specialties.

PSI has completed over $250 million in increasingly complex projects to date. Driven by our core values, we have positioned ourselves as an experienced and reputable contractor in various market sectors, including healthcare, OSHPD, high-end retail, entertainment, aerospace, tenant improvements, and pharmaceutical.

We pride ourselves in being a 100% employee-owned company providing unsurpassed quality and service.
