The culture of giving is vibrant at COS®.

Through personal involvement, our staff has raised considerable funds for their own charities. Enthusiastic staff teams are often formed to participate in charitable events.

Our organisation encourages and supports staff members who raise funds for the community.

Along with supporting these efforts, COS® seeks to deepen our culture of giving through the Lyone Foundation.

By providing a vehicle for staff to contribute, we hope to create a greater impact to funding recipients as well as our people through their giving experience.
