The Ontario Chaffey Community Show Band was founded in 1985 by the late, great R. Jack Mercer.  Our 2015-2016 season celebrates 30 years of outstanding music, continuing to pay tribute to the man who started it all.

Members of the band reside in over two dozen communities in Southern California.  The band rehearses on Monday evenings from 7 to 9:30 p.m. in the Jack Mercer Music Hall (building behind the auditorium) on the campus of Chaffey High School located at 1245 North Euclid Avenue in Ontario, between 4th and 5th Streets.  We always welcome new members, and there are no auditions.  Just stop by, bring your instrument, and sit in, wherever your playing level may be!

We perform monthly free concerts for the community at historic Gardiner Spring Auditorium and the Ontario Town Square Bandshell.  Check out SHOWS page for our performance calendar!  We are able to rehearse and provide music for the community thanks to the very generous support of our Sponsors and Donors including the City of Ontario, Chaffey High School, the Chaffey Adult School, Bellevue Memorial Park, The Mercer Family, The Ovitt Family, and the Ontario Community Foundation.  We're also extremely fortunate to have a wonderful network of volunteers that very generously donate their time and efforts to the band and the community.

The Ontario Chaffey Community Show Band is currently under the direction of Dr. Gabe Petrocelli and assisted by David Schaafsma.
