Five years after Heath Rushing was first elected to the Humble ISD board of trustees, his decision to resign in May was announced at a meeting Tuesday.

There is no timeline to name a temporary replacement or hold a special election, an HISD spokesperson said. The move was triggered by a job change. Rushing previously served as CEO of Memorial Hermann Northeast since 2015, before moving to serve as Senior Vice President and CEO for Memorial Hermann Katy and Memorial Hermann Cypress in February. Rushing's tenure in Position 6 was set to expire in May 2019, according to the district. "This is a very bittersweet announcement," Rushing said in a statement. "While I am excited about the professional opportunity and journey that lies ahead, I will miss everything about Humble ISD and the Lake Houston area community. I will always cherish the relationships built over the last 10 years.  The people of the Lake Houston area are what make it a special place to live, work and play." When he was elected in 2013, Rushing filled the position vacated by Houston City Council Member Dave Martin, whose district includes Kingwood and portions of Atascocita and Summerwood. Rushing served as chairman of the board’s Finance Committee and is a member of the Audit Committee and Technology and Data Governance Committee. He was heavily involved in discussions surrounding the district's next fiscal year budget, which could be approved in June, board President Keith Lapeze said. By stepping away, Rushing joins Brent Engelage, who decided not to run for re-election for the Position 5 seat in December. Elections for positions 1, 3, 4 and 5 will be held May 6. "I am proud of my service on the Humble ISD School Board and look back knowing that our schools are the reason why we live in a thriving community that represents the gateway where local business, global economy and quality of life come together," he said.
