The parish of the Holy Trinity where he was pastor for many years, alternating with three other Edmundite priests, was founded in 1964 as part of a response to the request of St. Pope John XXIII to send priests to Latin America. The parish was supportive of the work in the neighboring parish of Las Minas called Our Lady of the Rosary of Fátima. This support continued through the establishment of a program for children and teenagers called Rincon Infantile San Edmundo. Father Dubriske continues to help with this program, now divided up into several units because the Edmundites no longer have care of the parish in Las Minas.
On Sunday, September 15, he was the principal concelebrant of a Mass in a neighboring parish, which wanted to show their support for the suffering Venezuelan people. The occasion was the feast of the principal Venezuelan avocation of the Virgin Mary called “La Virgen de Coromoto.” Many of the Venezuelans who come to the monthly Mass in the Willow Wood residence were present for the Mass.
