Founded in 1851, the Parish of the Immaculate Conception, commonly known as Saint Mary’s, has served the spiritual and temporal needs of the people of Port Jervis and Deerpark for over 165 years.  Many of the families who comprise the parish today are descendants of those who established the parish and built our magnificent church, finished in 1871.

We invite you to join us in the celebration of Holy Mass and the Sacraments, in personal prayer, and in service to the wider community.  As you peruse this website, we invite you to become more familiar with what the parish has to offer, and hope that you will “come and see” for yourself!
