J.,
I highly recommend St. Elizabeth Ann Seton Catholic Church in Keller (off of Willis). I have been attending this church now for 4 years since moving to the area. My family and I enjoy the fellowship that we get with the church. Our children also attend the school. It's a beautiful church place. Here is a link to our website. http://www.seascc.org/
Good luck!
