A Message From Sr. Brid on the PIN program at Saint Columban
Many have been asking me about our PIN program, (Persons In Need) that we operated across the street at the White House and what we are doing now to help  during the Pandemic, so I thought I’d provide an update in our bulletin.  For those of you not familiar with this important program let me summarize it:  READ MORE

 Many of us are facing very particular challenges at this time. As a Catholic community in the Diocese of Orange, we are here to serve you and want to make you aware of the new Serve Hope Helpline, 844-279-0105. If you are in need of food assistance, crisis counseling, or spiritual guidance and prayer, we welcome you to call the Serve Hope Helpline at 844-279-0105.
