Teresa O'Brien

Teresa’s knowledge of both science and theology made working with an apostolate in apologetics for the complementarity of these two disciplines a natural fit. Her approach to teaching Catholicism, while mainly intellectual, is firmly grounded in and sustained by a life of prayer and participation in the liturgy and sacraments. Teresa has come to know God’s love for her and her love for God, which she hopes also to convey to all whom she instructs in the faith. Teresa’s three great passions of teaching, learning and protecting life are reflected in her volunteerism at the various parishes where she has lived: teaching RCIA and CCD at various grade levels, being involved in religious book study groups, and participating in Respect Life ministries.

Teresa has been married to her husband Michael since 1992. They have three grown children and live with a number of dogs and cats at any given time in Culpeper, Virginia, where they are active at Precious Blood Catholic Church.

CAINA’s Speaker Fee Policy

The Catholic Apologetics Institute of North America (CAINA) does not have a fixed fee for speaking engagements, since we offer our presentations as a service to God and the Church and for the spiritual edification of attendees. In the spirit of this mission, CAINA will accept the hosting organization’s customary stipend for invited speakers (normally at least $100 per talk) to help defray operating expenses and have the means to reach a greater audience.
