Rally Day Blood Drive

Be not afraid--give life. As part of the Cathedral's Rally Day celebration, parishioners and neighbors are invited to donate blood and help support patients throughout the Houston area. A single donation can make a meaningful difference for people facing surgery, serious illness, injury, and other medical emergencies. Appointments are encouraged, and eligible walk-in donors will be welcomed as space permits. Please bring a photo ID and allow time for registration, a brief health screening, the donation, and refreshments afterward. Schedule your appointment:
