Marin County has successfully appealed to the California Department of Public Health (CDPH) to move into Tier 2 of Economic Reopening, allowing more businesses to reopen. Churches are allowed to open with 25% capacity or 100 people, whichever is fewer. This week, cleaners will do the deep cleaning of the interior of the church building, then St. Isabella Church can reopen. Check back for latest updates on the date.

Mission statement

The mission of St. Isabella's Parish is to create an atmosphere in which faith can grow. This is accomplished through preaching the Good News, the sacramental celebrations, the offering of Eucharist and eduction of the primary, secondary and adult levels. We wish to establish lines of communication and the exchange of ideas through listening to the faithful and implementing those ideas which would benefit the community. Our intent is to reach out to all age groups from children to our older parishioners. Being aware of those less fortunate, we minister to their spiritual and physical needs. Finally, we are aware that whatever growth does take place, it is due to the working of the Spirit.
