San Pedro Relay for Life

Holy Trinity's Team “Jolly Fr. Rolly” needs walkers!
Help us in remembering Fr. Rolly Jardiniano, who lost his battle with cancer two years ago. Join our team as we help to raise money, in his name, for the American Cancer Society.
Sign up to walk just 1 hour with us as we remember all those who have won or lost a battle against cancer.
24-hour walk is kicked off by 10am Invocation by our very own Fr. Laurence Gallagher.
