Red Cross Blood Drives

Mater Dei High School is pleased to sponsor 2 blood drives each school year with the American Red Cross.

Give blood. Help save lives.

All members of the Monarch family are encouraged to donate. Students must be at least 16 years old to donate and if you are 16 you must provide a Consent for Blood Donation signed by a parent/guardian (see Parental Consent form below).

(Previously the Red Cross would say that each donation could save up to 3 lives, but now the official verbiage is “each donation saves at least 1 life).
