Rushbrook joined the north maintenance unit in May 1987. The majority of his time at NIH was spent as the senior building engineer for Bldg. 31. "Craig was always there with a smile to provide whatever service was needed by the building occupants," according to a tribute flyer produced by several of his coworkers. "As a first line supervisor, Craig was well liked and respected by the employees he supervised. He was always willing to share his knowledge and help with the daily duties required to operate each building. Craig will be deeply missed by all who knew him. Part of Craig will always be at NIH in the employees he trained during his years of service."

A donation for his family is being collected at Parley's Place, the concession stand in Bldg. 31.
