Buffalo Grove opened in 1973, drawing students and staff from Wheeling and John Hersey High Schools. Dr. Clarence M. "Chick" Miller, formerly assistant principal at Wheeling High School, was named the school's first principal. On March 12, 1976, President Gerald Ford, during his campaign against former California Governor Ronald Reagan, made a March primary appearance in the gymnasium of Buffalo Grove High School. In 2003, new classrooms, a foyer, and offices opened as part of a six-million dollar new development. The "circle drive" on the west side of the school was greatly reduced in size to make room for the new classrooms and foyer. The new classrooms included new science labs and special-ed facilities. Additionally, room was made in old storage space on the second floor of the south side of the building for new foreign-language classrooms. On August 27, 2004, the Bison hosted their first Friday night game under new lights at Bison Stadium. They were the final team in the Mid-Suburban League to switch from Saturday afternoons to Friday night games.

A renovation of the school in 2014 added a multimillion-dollar pool area. Competitive teams from Buffalo Grove HS compete in the Mid-Suburban League.
