The Four Quadrants Logo
The four quadrants of the Chestnut Health Systems™ logo represent leaves that pay tribute to our name and historical identity. The original Chestnut logo depicted three Chestnut trees.
Each quadrant represents one of our four core service lines: substance use treatment, mental health treatment, primary care, and research. The leaves come together in a way that represents integration. We strive to provide whole-person care to all who come to us for help. The negative space between the quadrants creates a medical cross, which symbolizes health care.
The colors of the logo are also symbolic. Gray, the anchor color, represents a stable base from which the new and positive can come. Blue symbolizes loyalty, strength, wisdom, and trust. It has a calming effect. Green enables both mental and physical relaxation and is beneficial in the treatment of depression, nervousness, and anxiety.
