Mark Thomas,
Music Director



Mark Thomas has worked extensively in six states, over the course of 30 years as a jazz and classical pianist, organist, conductor, composer, bandleader, percussionist and studio musician. For 19 years he was the music director for three different cathedrals and their dioceses before returning to Colorado to serve St. Thomas Aquinas as music director in September of 2009. One of his greatest passions is inspiring people from all walks of life, amateur and professional musicians alike, in the mysteries of the faith through liturgical music. 

Mark has performed concerts in San Francisco, Chicago, New York and Boston and was the house jazz pianist and band-leader at the renown White Barn Inn in Kennebunkport, Maine, playing weekly for celebrities and dignitaries which included two presidents. He has premiered music for organ by Philip Glass, Arvo Pärt, Henryk Gorecki and Morton Feldman, and has conducted numerous US premieres of Irish composer Michael McGlynn’s choral music as well as the North American premieres of Arvo Pärt’s The Beatitudes and Pärt’s epic Berlin Mass for choir and orchestra. His own compositions have been performed around the world with milestones at St. Peter’s Basilica at the Vatican, San Marco in Venice, Trinity College in Dublin, Boijmans Van Beuningen Musem in Rotterdam, St. Stephen’s Cathedral in Budapest, the Basilica of the National Shrine in Washington, King’s Chapel in Boston, the St. Lawrence Center at the University of Kansas and by the Charleston Symphony Orchestra and the Spoleto Festival, and the Grand Rapids Symphony Orchestra.  His composition, Ave Maris Stella published by Earth Songs, was featured at the annual conference of the American Choral Directors Association (ACDA) and his own organ compositions have been presented on American Public Media’s Pipedreams. Undergraduate studies were at the University of Dayton, he received a master’s degree in composition from CU Boulder and did doctoral work at SUNY Buffalo.  He and his wife Leanne have two children and six grandchildren that are the joy for their hearts
