On Thursday, Sept. 20, Springfield Ball Charter School (SBCS) will open its doors to alumni, former staff and teachers, current students and future students alike, as it commemorates its 20th anniversary.

The family-friendly event will take place from 5:30 to 7 p.m., and like the school’s first birthday celebration, will include a performance of the school song by the SBCS Junior Glee Club, as well as a celebratory parade led by the Springfield Southeast High School band.

A bounce house and refreshments also will be available, and the evening will conclude with a guided school tour.
