Thank you for your interest in St. Mary School. Founded in 1871, the school has a rich history in the community of Gilroy and enjoys active partnerships with our families to provide a quality Catholic education while fostering a welcoming community of faith.


Applications are available year round, and we start accepting applications for the following school year in November.  So that prospective families can see St. Mary School and what we offer, we host three open houses during the school year (November, January and March) to which prospective families are invited to attend. During Catholic Schools Week in January, the open house is held during the school day so that families can observe the classes in action. One-on-one tours are also available anytime during the year, and families are invited to contact the school office at (408) 842-2827 to schedule a tour.


If you have any questions, please contact the Admissions Director at (408) 842-2827 or for more information.  Thank you for taking the time to consider St. Mary School for your child’s education. We look forward to processing his/her application, and it is our hope that you will join the community of St. Mary School.
