As the population of Tyler and Smith County grew, the Cathedral parish expand as well. In the early 1990s, the parish added the Cathedral Center, featuring meeting and banquet rooms for parish activities. In 1994, with thousands attending Masses every weekend at the Cathedral, there became a need for an additional space. The parish created St. Paul’s Chapel in the Chancery Office as a temporary facility while it planned a permanent location. The patience of the parishioners was rewarded on December 8, 2011, when Bishop Alvaro Corrada dedicated the 700-seat Chapel of Sts. Peter & Paul on the campus of Bishop Gorman Regional Catholic High School.
