Our Faculty

 Called a “singer’s conductor,” Christopher Berry came to be a choirmaster almost accidentally. His education and experience were initially focused on organ performance and improvisation, but, through his work as accompanist for acclaimed conductors and ensembles, he developed a passion for choral music. 

His early experiences working under Robbie Giroir at the Cathedral in Baton Rouge introduced Mr. Berry both to the organ and the beauty of Gregorian chant, but the next few years of his life were focused primarily on organ study. Berry went on to study organ performance with Jesse Eschbach at the University of North Texas, followed by graduate work with James Higdon at the University of Kansas. While at the University of Kansas, he laid the foundation for his choral career by studying conducting with Michael Bauer. At that time, he also had the opportunity to work with Simon Carrington, an experience that was formative. Meanwhile, Mr. Berry spent a summer in Paris to study with Marie-Claire Alain and Madame Duruflé. His time with all these teachers left him with a love of early music that continues to this day. 

Toward the end of his studies, Mr. Berry was awarded a Rotary Foundation Ambassadorial Scholarship from 2000–2001 to study in Paris. There he worked with François-Henri Houbart at the conservatory of Rueil-Malmaison, where he was awarded a Premier Prix at the culmination of his studies. While his time in Paris was primarily intended for organ study, it also provided the opportunity to sing under the baton of Ned Tipton as well as with the Choeur Gregorien de Paris. He audited a course at the Paris Conservatory in Gregorian chant conducting under Louis-Marie Vigne. These experiences fed Berry’s burgeoning love of chant and choral singing, and would change the course of his career. 

Returning to the states in 2001, he was finally able to occasionally take the baton himself under the direction of Peter Latona at the National Shrine in Washington, D.C. He then moved to New York, where he was able to form a new ensemble at Holy Trinity RC on the Upper West Side that sang a full program of chant and polyphony. At the same time, Mr. Berry was gaining insight into working with choirs as an accompanist for Andrew Megill, Anton Armstrong, and Dale Warland at Westminster Choir College. He was able to glean tremendous insight into how to shape choral sound while observing these conductors at work. He was soon able to apply this knowledge in his work with seminarians.

As the Director of Music for the Pontifical North American College in Rome, Mr. Berry had the opportunity to explore the repertoire of Gregorian chant while training the seminary choir to sing at ordinations held in St. Peter’s Basilica. While in Rome, he conducted a concert in the Sistine Chapel for Patrons of the Chicago Symphony, and recorded Regina Immaculata, to celebrate the college’s 150^th anniversary. 

Upon his return to the states in 2009, he took the helm at Church of the Incarnation in Dallas, where he cemented his reputation as a choral conductor. There, he led choral residencies at Canterbury Cathedral, St. George’s, Windsor, Westminster Abbey, and Litchfield Cathedral, where he received perhaps the greatest compliment a choir can receive, “You are an English cathedral choir,” from the cathedral Precentor.

Since then, Mr. Berry has developed a reputation for bringing choirs to new heights. A short time after arriving in Milwaukee and establishing a new choir at the Basilica of St. Josaphat, the group was asked by the AGO to sing a three-choirs concert, along with the choirs of the Catholic and Episcopal cathedrals. In 2015, he made a choral recording, Pax Tibi, featuring some of the beloved repertoire of that majestic church. 

Since 2019, Mr. Berry has been director of music at St. Stanislaus Oratory in Milwaukee, directing its choir and establishing new ensembles. Trained in semiology during his time in Paris, he has had to become an expert in the Classic Solesmes method for his work for the Institute of Christ the King. In his “free time,” he is enjoying delving into the scholarship behind the mensuralist approach to chant. He is a sought-after clinician, and he has most recently been on the choral conducting faculty of the Church Music Association of America Colloquium. 

Mr. Berry lives just south of Milwaukee, though his heart is ever in his native South, where he grew up playing music, soccer, and visiting Civil War battlefields. He still loves those things today, along with newfound interests—but most of all, any and all time spent with his beloved wife and six daughters. 

Frank La Rocca is Composer-in-Residence at the Benedict XVI Institute for Sacred Music and Divine Liturgy.

His commissioned works for the Institute comprise, thus far, four Masses: Messe des Malades (2022), Missa Sancti Juníperi Serra (2022), Requiem Mass for the Homeless (2020) and Mass of the Americas (2018). Mass of the Americas has been hailed as “Perhaps the most significant Catholic composition of our lifetimes” and “a cornerstone of modern liturgical composition.” The recent CD recording of this Mass debuted at number one on Billboard’s Classical charts and earned a place in the Top Ten for Traditional Classical music for 2022. Other recent distinctions include winning the ORTUS international choral composition competition, and a 2018 American Prize for his A Rose In Winter – the life of St. Rita of Cascia, a major work for chorus, orchestra, and soloists. As Composer-in-Residence at the Benedict XVI Institute, La Rocca oversees the commissioning of works by rising young Catholic composers—a total of six to date.

He has received grants, commissions and awards from the National Endowment for the Arts, California Arts Council, the Foundation for Sacred Arts, Young Women’s Chorus of San Francisco, Diocese of Oakland, California State University, ASCAP Foundation, USC Thornton Chamber Singers, Vanguard Voices, London Festival of Contemporary Church Music, Cois Cladaigh, the Madrigirls, and many others. His work, Diffusa Est Gratia was toured by the renowned London Oratory School Schola Cantorum in Fall 2017 in Boston, New York and Washington, D.C.

His first solo CD In This Place (Enharmonic Records) reached the top ten in classical CD sales on Amazon and was a 2013 “Critic’s Choice” at American Record Guide.

Trained as an academic modernist during his degree studies at Yale and University of California-Berkeley, La Rocca came to see this approach as a barrier to authentic musical expression, and spent many years in search of a personal creative language—leading him into the realms of philosophy and theology and, ultimately, back into the Catholic Church at Lent in 2009.

His catalog includes works in all genres, with an emphasis on sacred choral works. At a recent University of Notre Dame conference, “James MacMillan: The Musical Modes of Mary and the Cross,” La Rocca presented a talk entitled, “The Apologetics of Beauty: a Musical Theology of the Incarnation,” based upon his choral work O Magnum Mysterium.

In 2014 he retired from a 35-year career teaching music composition and theory at California State University East Bay, where he is now Professor Emeritus. He was a founder of and Executive Director for the San Francisco-based new music concert series, Composers, Inc., for 25 years, overseeing the performance of over 500 works by living American composers.

Dr. La Rocca was inducted into the American Association of Catholic Artists and Scholars in 2023. He is published by Boosey and Hawkes, Walton Music, Santa Barbara Music, and Lumen Verum Music.

William Mahrt is Associate Professor and Director of Early Music Singers in the music department at Stanford University, President of the Church Music Association of America, and editor of Sacred Music, the oldest continuously published journal of music in North America.

Dr. Mahrt grew up in Washington state; after attending Gonzaga University and the University of Washington, he completed a doctorate at Stanford University in 1969. He taught at Case Western Reserve University and the Eastman School of Music, and then returned to Stanford in 1972, where he continues to teach early music. Since 1964 he has directed the choir of St. Ann Chapel in Palo Alto, which sings Mass and Vespers in Gregorian chant on all the Sundays of the year, with masses in the polyphonic music of Renaissance masters for the holy days.

His research interests include theory and performance of Medieval and Renaissance music, troubadours, Machaut, Dufay, Lasso, Dante, English Cathedrals, Gregorian chant, and Renaissance polyphony. He has published articles on the relation of music and liturgy, and music and poetry. He frequently leads workshops in the singing of Gregorian chant and the sacred music of the Renaissance.
