George S. Parker High School

George S. Parker High School is a comprehensive public high school located on the west side of the city of Janesville, Wisconsin. The school, named for George S. Parker, founder of the Parker Pen Company, is a part of the School District of Janesville and was constructed in 1967. The rival east side school is Joseph A. Craig High School.

In Nov 2006, a referendum passed that provided nearly $71 million for updates and renovation to both Parker and Craig High Schools. Construction began in October 2007 and lasted two years.
