- The building is based on the Clark County Government Center. The college itself is based on the University of Nevada, Las Vegas. The college is possibly named after David Greenglass, an American-born Soviet spy who worked in the Manhattan project.
- Katie Zhan probably studied nursing in this college. This is because she can be seen in pictures in some safe houses with the Greenglass College on the background. The presence of bio-hazardous waste dumpsters within the college's dependencies indicate the college offers medical courses.
