Diocesan/Trinity Publications began over 40 years ago in a small printing office in Michigan. Bob Zielke, our founder, bought a small printing company in the 1960's and at the request of a local parish priest, began printing their weekly bulletin. Our Michigan office serves St. Isidore's Church to this day.

Diocesan/Trinity Publications was one of the first parish publishing companies to accept digital copies of the bulletin, to provide one-on-one client training in the publishing software of the parish's choice, to submit bulletin files electronically, to offer glued-in inserts and full color covers.

Today, we have grown to five offices, including our corporate headquarters in Austin, TX: Trinity Publications. We also maintain Diocesan Publications locations in Columbus, OH; Harrisburg, PA; Grand Rapids, MI and Orlando, FL. Diocesan and Trinity Publications now serve over 1,500 parishes nationwide at no cost to the parish.

As our rich history has shown, we are as committed as ever to serving the needs of the Church and we are constantly striving to bring you excellent service, friendly and knowledgeable staff and more resources to help make your parish life better.
