The Rev. John Boonzaaijer — Head of School


Born in Michigan to a Dutch immigrant family, John worked in the family’s European Pastry Bakery, as one of nine children. After eight years in his first pastorate in Sand Springs, Oklahoma (1994-2002), he and his wife Christine moved to Tyler, Texas, to teach and administrate in the parish school of Good Shepherd Reformed Episcopal Church and School, as Assistant Rector. He has served as Rector of The Chapel of the Cross (REC) since 2007, where he and Christine also began The Saint Timothy School in 2008. Driving truck cross country for a year between his curacy and first pastorate provided some of his best training for life “on the docks.” Each of the five Boonzaaijer children fills and nuances their full and colorful home.

Education: Christian Reformed School System (Kalamazoo, MI), and homeschool; B.Th. (1991); curacy (1993); M.Div. (2004); Th.M. (2009). As Head of School, Fr. Boonzaaijer leads daily Morning Prayer, and also teaches Upper School Mathematics and Middle School Bible; his favorite hobbies include working on boats and sailing them, woodworking, karate, piano, reading, and baking bread. His writing and seminars develop and apply parish life as “the good life,” extending from the altar of worship, and on traditional catechesis. He believes a true parish school in the Anglican Tradition develops a capable, knowledgable, virtuous, and devout student in any walk of Christian faith.

The Rev. Jonathan Trebilco — Administrative Principal


Fr. Jonathan comes from a missionary family: his parents were career missionaries in Vietnam, Indonesia, and the U.S. He lived in Indonesia as a child but was mostly raised in Northern California, where his parents ministered to Southeast Asian immigrants.

Years ago he went on a spiritual journey to discover the meaning of historic Christian worship.  That journey led him to the Book of Common Prayer and the Anglican way.  He was confirmed in the Reformed Episcopal Church by Bishop Dan Morse in 2004.

Fr. Jonathan has a B.A. in Biblical Studies from Trinity College of the Bible and Theological Seminary (Newburg, IN—accredited by the University of Liverpool and Canterbury Christ Church University, UK). He moved to Houston in 2006 to attend Cranmer Theological House. He graduated summa cum laude from Cranmer House, with an M.Div. in 2009, was made a deacon that same year, and was ordained a priest in 2010.  In Houston, he met and married his wife Sommer Bridges in 2008.

Fr. Jonathan served as Associate Rector at St. Francis under Dr. Curtis Crenshaw for four years. After Dr. Crenshaw announced his retirement, Fr. Jonathan received a call from the Vestry of the parish and was installed as Rector by Bishop Royal U. Grote Jr. in 2014. He served as Rector of St. Francis for five years. 

In addition to pastoral ministry, Fr. Jonathan was involved with teaching and curriculum development at two classical Christian schools in the greater Houston area, and served as thesis advisor to seniors completing their senior theses each year.  He also spent six years in prison ministry to young offenders as assistant to the Protestant Chaplain at what was then the largest youth prison in the state of California.

Fr. Jonathan and Sommer Trebilco joined The St. Timothy School faculty in the summer of 2019. They have a three year old daughter, Gabrielle.
