MRCC Staff

Our Staff

The Retreat Center could not operate effectively without a competent and dedicated staff.

Nathan Martin

Executive Director

Nathan comes to the Marianist Retreat Center from the Society of St. Vincent de Paul’s National Council, where he spent over nine years in fundraising. Before that, Nathan worked for the National Alliance on Mental Illness – St. Louis as their Director of Development. While attending Duchesne High School, Nathan participated in a retreat at the Marianist Retreat Center. Now, many years later, he serves as their Executive Director. As a parishioner at St. Cletus in St. Charles, MO, Nathan attends Mass with his wife, Rachel, and son, Trace. For fun, Nathan enjoys spending time outdoors, especially at the “family farm” that was originally owned by his great-grandfather. You can reach Nathan by email at

Jen Duncan

Director of Hospitality

Jennifer comes to us as a retreatant and retreat director that loves the Marianist Retreat center. Jen has served the past few years as the Campus Minister and Teacher at Bishop DuBourg High School. She is currently finishing up the school year there while working part-time for MRCC. At the end of the school year, Jen will be full-time at the center. Her primary role will be overseeing the day-to-day operations, scheduling, and contracting for retreats at the center. Please join me in welcoming Jennifer Duncan to the Marianist Retreat and Conference Center. To reach Jennifer, please email her at

Paul Masek

Director of Programs

Paul Masek has been married to his beautiful wife Lisa for over 30 years, they have four incredible adult children, and for fun he love hunting, fishing, camping, hiking, and telling dad jokes. He is the funniest person he knows, though his wife says he doesn’t know enough people (so maybe she is funnier)! His history with MRCC goes all the way back to 1981 when he attended a retreat here as a high school senior at Mercy High School. He brings over 30 years of retreat ministry experience with young people of all ages, and recently received his certificate in Spiritual Direction from the Archdiocese of St. Louis’ Catholic Renewal Center. Paul believes that God always has something MORE in store for us! You can email Paul at or you can call or text him at 314.608.5447
