Tomball ISD names PBK designer for district's second High School The Tomball ISD (TISD) announced this week that PBK will serve as architect for the programming and design of the District�s newest high school. Only the second high school in the community, the new campus will accommodate 3,000 students (core) and is scheduled for completion in 2011. This project is part of a $198 Million bond program that was approved by TISD voters in May 2007. PBK has enjoyed an existing relationship with the TISD since 2002, and served as architect for the "extreme makeover" to the original Tomball High, which won the prestigious Caudill Award from TASA-TASB in 2004.
