Parish Mission

We are a vibrant, faithful, Eucharistic, Catholic community who bring people to Christ and send them out to transform the world.

Saint Gregory the Great exists to help nurture and enhance a relationship with God. As we live by faith, God is able to use us and cause us to grow in grace. God is able to make big changes in our lives, and through a process of trusting Him we can experience great joy.

Living in faith is a process that evolves and grows over a lifetime. We are committed to walking with you on your faith journey in order to help propagate a deeper love of God through all aspects of parish life.

Should you have questions, or need assistance, please contact us at your convenience.
