Meet Our Priests





Fr. David Medow - Pastor

Fr. David MedowFr. David Medow, Pastor of St. Mary Immaculate Parish, arrived on the staff here in July, 1998.  He became the Pastor of the parish in June, 2005.
A native of Chicago, Fr. David is notable for being a married priest.  He was raised a Lutheran and was ordained a Lutheran minister in 1985, serving for nearly 12 years.  He was received into the Roman Catholic Church on November 1, 1996 by Bishop Joseph Imesch and received permission from Rome to begin a course of study for the priesthood.  Fr. David is one of about 150 married Roman Catholic priests in the United States:  the Holy Father occasionally gives permission for the ordination of married, former clergy from  other denominations who become Catholic and complete at least three years of training for priesthood. Currently, Fr. David is the only married priest in the Joliet Diocese and one of only a small handful in the Midwestern United States.             

Fr. David attended public schools in Chicago, Georgetown University in Washington, D. C.  He received an MA in Theology from Oxford University in England and a Masters of Divinity Degree from the Lutheran School of Theology in Chicago.  He has nearly completed his work for a Doctor of Ministry Degree and Licentiate in Sacred Theology from Mundelein Seminary.

Fr. David and his wife Jane (who has always been Catholic) have been married since 1979.  Jane has actually been a member of the St. Mary's staff longer than Fr. David.  She has been a member of the Parish School Faculty for 18 years. David and Jane have a son, Nikolai and a daughter, Hannah. The Medow's dog, Dusty, would also want to be included in the list of family members.


Fr. David Mowry - Parochial Vicar

Father David Mowry was born July 11, 1987, to Joan and Keith and was baptized on October 25 of the same year. After a few years in Elmhurst and a move to the Washington D.C. area, his family returned to Illinois and settled in Glen Ellyn. Fr. Mowry attended parochial school at his home parish of St. Petronille and graduated from there in 2001. He began to discern a call to priesthood in his junior year at Glenbard West High School, and, in the fall of 2005, he entered St. John Vianney College Seminary at the University of St. Thomas in St. Paul, MN. He graduated from the University of St. Thomas in 2009, and entered Mundelein Seminary in the fall of the same year.  

He was ordained to the diaconate on June 2, 2012, and served as a deacon at St. Joseph Catholic Church in Addison. His ordination to the priesthood came on May 18, 2013, and in June of that year he began his assignment to Immaculate Conception in Elmhurst as associate pastor until 2016. His brother Trevor (26) serves as co-principal oboe for the United States Marine Band, and his sister Elizabeth (15) will be a sophomore at Glenbard West High School in the fall. 



Fr. John Regan - Priest-in-Residence

I am grateful that Bishop Conlon has assigned me to serve as a parish priest at St. Mary Immaculate. I was ordained in 1989 and began serving as a parochial vicar at St. Liborius Parish, in Steger. From 1993 to 2006 I served as the Joliet Diocese Vocation Director. In 2006 I was named pastor of St. Walter Parish, in Roselle. Since July 2008 I have been on a leave of absence from public ministry. In March of this year Bishop Conlon assigned me to St. Jude Parish, in Joliet, to begin the transition back to priestly ministry. In addition to serving as a parish priest at St. Mary Immaculate, I also work a secular job, currently in a local factory.

I look forward to celebrating Christ’s presence in the daily situations of our lives and sharing the Good News of God’s love and mercy. God is Good … All the Time.
