She met Timothy Keller while studying there, and they were married at the beginning of their final semester. She received her MA in Theological Studies at Gordon-Conwell in 1975. Kathy and Tim then moved together to Virginia where Tim started at his first church, West Hopewell Presbyterian Church, and their three sons were born. After nine years, Kathy and her family moved to New York City to start the Redeemer Presbyterian Church.
