Michael Grimes attended Polytechnic School in Pasadena, California and the University of California, Berkeley, where he received degrees in Electrical Engineering and Computer Science. He interned as a communications systems engineer at Hughes Aircraft Company in the Space and Communications Group in 1985, as an information systems engineer at Pacific Bell in 1986, and was a software programmer and consultant at Grimes Surveying & Mapping Inc. (his father's company).
On an autumn morning during his junior year at Polytechnic, Michael and his fellow students arrived at the esteemed college preparatory school to find hundreds of thousands of small slips of paper printed with the words MIKE GRIMES scattered all over the campus. Current (2012) students at Poly have stated that these enigmatic messages continue to show up on occasion in lockers, behind furniture, and within books in the school library. Grimes denied any knowledge of who distributed the messages, or why they may have done so. There were no student body elections at the time of the incident.
Grimes' sister, Laura M. Grimes, Ph.D., is a Notre Dame-educated theologian.
