During World War II when Americans were supporting the war effort at home, they realized the lifesaving importance of blood transfusions. For many communities, it created a new social responsibility to ensure a safe and adequate blood supply.

At that time the blood banks nearest to Denver were in Dallas and Kansas City. Dr. Osgoode Philpott and philanthropist Helen G. Bonfils recognized the need for a local community blood bank. In 1943, with a diverse group of community-minded people they founded Belle Bonfils Memorial Blood Bank, named after Helen’s beloved mother.

In 2017 Bonfils merged with Blood Systems, one of the nation’s oldest and largest transfusion medicine organizations – and a fellow nonprofit. Headquartered in Denver, Blood Systems’ Mountain Division consists of Bonfils Blood Center operations in Colorado and United Blood Services (UBS) operations throughout Wyoming, western Nebraska and southwestern South Dakota. Together, Bonfils and UBS need to collect approximately 3,500 blood donations each week to support patients at nearly 140 hospitals and healthcare facilities.

Together, Bonfils Blood Center and Blood Systems will continue to make a difference in our community by producing a safe and stable blood supply, inspiring individuals to donate blood and advancing lifesaving research.
