Clergy & Staff

Fr. Brian Larkin, Pastor

A Colorado native, Fr. Brian Larkin grew up as the middle child of three boys in the foothills southwest of Denver. Fr. Brian was on his way to becoming an accountant when God set a new trajectory on his life by calling him to priesthood. FB (as some call him) is addicted to coffee, the beauty of the mountains, ’90s music and most importantly, following Jesus.

Fr. Sean Conroy, Parochial Vicar

Fr. Sean Conroy grew up in the foothills southwest of Denver and is a proud graduate of Mullen High School. He had a powerful conversion throughout high school in which God called him from life of dissipation to a life of grace. Though he tried to run from God, the Lord continued to pursue him and call him to be a priest. He couldn’t run forever. He loves sports and staying active in the beauty of the mountains. His greatest desire in the Church is to be able to do ministry in the backcountry. Fr. Sean loves mountaineering, cycling, skiing, hockey, and Jesus!

Fr. Witold Kaczmarzyk, Parochial Vicar

Fr. Witold Kaczmarzyk was born in Ostrow Wielkopolski, Poland. Right after high school, he became a student of the faculty of physics at Warsaw University of Technology in Poland, which is like MIT in Boston, MA.

In Warsaw, he experienced a conversion and his vocation “came to the surface.” He made a decision to attend a seminary and develop his faith seriously. Prior to entering Major Seminary in Kalisz to study philosophy in 2012, Fr. Witold walked the Camino de Santiago in Spain – French route (Way of St. James) – almost 500 miles on foot in one month. It was a very deep spiritual experience.

In 2016, Fr. Witold became a seminarian of the Archdiocese of Denver, and was involved in the Totus Tuus summer program, Catholic Charities, and served his diaconal internship at the Cathedral Basilica in Denver. In May 2019, he was ordained and assigned to Christ the King Parish in Denver as parochial vicar. In July 2021, he was assigned to Our Lady of Lourdes Parish and St. Louis Parish as parochial vicar.

Fr. Witold has always liked sports and while in seminary began to train for long-distance running with his peers. Within two years, he completed five major marathons (26.2 miles) in Poland. For this achievement, he received the Crown of Polish Marathons. He loves traveling and has visited 17 countries around the world.

He hopes that his studies and experience will help to serve these parishes as much as possible. He is thrilled to be a part of OUR parish. “Pray for me so I will do my best!”

Deacon Mladen Martinovic

Deacon Mladen has served St. Louis Catholic Parish since his ordination in 2015. Taken from Denver Catholic, “When his country was occupied by Communists, the secret police tried to squash the faith of its citizens. As a young boy, Deacon Mladen Martinovic said he had a strong faith and felt the call to serve God. ‘I had to talk to everybody about God,’ he said. But, the government demanded citizens deny God in public, but he wouldn’t. From 1984-1991 he was taken from school and into police headquarters where he was subjected to long periods of persecution in a dark room. He eventually fled to Germany with his uncle, nearly escaping death. ‘I left my country but the calling was still there. It never stopped,’ he said. He married his wife in Germany and they came to Denver in 1997. He began to learn English and the call to the diaconate returned. ‘I think God is always the one who planted it,’ he said. With his wife’s witness and support, he was able to go through formation.” Deacon Mladen has served the Croatian community at St. Louis Parish in Englewood since his ordination.
