The largest hospital system in California's San Joaquin Valley, Community Medical Centers operates 16 major health facilities and employs 6,300 people. Corbin developed sign systems for many of those facilities, including Community Regional Medical Center—Community's flagship hospital and part of a 58-acre medical campus in the heart of downtown Fresno.

The exterior sign systems use shapes that reflect the diamond in the corporate brand identity. Blue and dark grey are used to establish an anticipatory value with the viewer, while certain historic buildings received customized framing details that align with the architecture.

Interior signs use soothing colors and photographic imagery to enhance the health care provider's healing environments. The use of paper inserts allow for fast, economical updating as locations and room functions change.
