Most Holy Trinity Catholic Church is the newest Catholic community within the Archdiocese of New Orleans located in the Covington/Mandeville area on the north shore of Lake Ponchatrain approximately 30 miles from New Orleans.

The Parish was founded because of the demographic shifts in population as a result of Hurricane Katrina. Also many of the religious objects used in Church came from Churches closed or heavily damaged by the hurricane.

We are striving to become a vibrant Christ-centered community that is prayerful, welcoming and share a common vision: God is the source of all!

The purpose of this website is to keep our parishioners and visitors informed of what is going on here at Most Holy Trinity.  Our hope is that by becoming involved and using our God-given talents, we can help build the Body of Christ on Earth.
