In the spring of 1974 Bishop Francis J. Green, of the Diocese of Tucson, made the request for a Christian renewal center to be established in Cochise County, the southeast corner of the diocese.

Abbot David Geraets, O.S.B. of the founding Benedictine Abbey, Pecos, New Mexico, asked Fr. Louis B. Hasenfuss O.S.B. to begin the project. He arrived in St. David from Albuquerque, accompanied by Paul Meuller and Steve Stevens, on September 3, 1974. They settled in on the 92 acres property. Maxine and Larry Lee, a married California couple, and Fr. Clark Moore, a Tucson Diocesan priest, were there with Marty Martinez. From this nucleus the Monastery grows today.

On December 12, 1974 the ground was broken for Our Lady of Guadalupe Church, with Bishop Green presiding over the historic occasion. He also presided over the church dedication on June 24, 1981. 


As good stewards of the land, ecology and environment are important to the Holy Trinity Center community. On the 132 acres, there is not only the Lady of Guadalupe Chapel, living quarters, offices, library, museum, dining hall, Father Louis Hall, and conservatory, but guest houses for the retreats.

The enclosed court yard around the church is a gardener's delight with the rose garden, flowers and plants of many varieties. The lovely fountain, surrounded by benches, gives the visitor an opportunity to just sit and soak in the peace. Another rose garden is down in the plaza near the gazeboes and library.

Many pecan trees provide a means of income.


In 1992, the Bureau of Land Management helped dedicate a 1.3 mile bird sanctuary trail that borders along the property and the San Pedro River. In 1993 the monastery received the "Conservation Co-operator of the Year" award presented by San Pedro National Resource Conservation District.

With the beauty of the large, tree lined pond, visitors attain a peace and solitude that is difficult to find in a busy world. A Oriental garden is also a place for meditation. It has a small pond, oriental bridge and lovely flowers to lend its feeling of serenity.

Visitors who have their own recreational vehicles can stay in the Monte Cassino RV Park housed on the property. During their stay, they are invited to join the community in daily prayer and Eucharist, plus other activities.
