I am a native Texan, born in Forth Worth, I grew up in Weatherford, Texas, where I attended public school. I attended Holy Trinity Seminary and the University of Dallas.

I enjoy reading, especially history and politics; gardening; travel; photography; scuba diving; and snow skiing. It is challenging to lead such a large and diverse community as St. Monica, but I especially enjoy the opportunity to be part of a parish family with so many inspiring people who share their time and their talents in so many ways to make this such a wonderful and welcoming place.
