Welcome to the 2025-2026 Season, the 40th concert season of the Ontario Chaffey Community Show Band!  This year we look forward with great excitement to our upcoming concert season.  Please check our website for the tentative show schedule.  Currently the membership of the Ontario Chaffey Community Show Band is comprised of a wide variety of occupations from doctors, lawyers, dentists, mechanics, educators, and other professions.

Dr. Gabe Petrocelli retires and turns the Show Band over the new Director, Patrick Arnold, at the end of the concert on June 16th, 2025.

We are excited to start this season on Monday, September 15th in historic Gardiner W. Spring Auditorium, located on the campus of Chaffey High School.  The concert titled "Back To Our Roots" will be filled with musical highlights from the past 40 years of Show Band entertainment performed for the City of Ontario and our local communities.  We'll have an exciting repertoire of various music genres including marches, swing, rock 'n' roll, and Latin music.  Guest artists will be Brian Detwiler and Marilyne Sherwood.

For four decades the Show Band has been performing one free concert a month for the Greater Ontario Community, bringing in an array of talented guest artists as well as providing musical performances for various city-sponsored events.  The Show Band is now under the direction of Mr. Patrick Arnold, retired local high school band director and featured tenor sax soloist, along with two assistant conductors:  Mr. David Schaafsma and Mr. David Grasmick.

The Show Band continues to grow as we add tremendous new talent to our band.  We feature many of our own musicians as conductors, vocal and instrumental soloists, and also welcome a talented array of guest artists to our programs on a regular basis.

The Ontario Chaffey Show Band relies on the generous donations of sponsors and financial support from the City of Ontario to help keep our programs running.  Additionally, a non-profit organization called "The Friends of the Ontario Chaffey Community Show Band" helps to provide assistance to the Show Band.  If you enjoy the Show Band performances, please consider making a tax-deductible and secure payment via our PayPal account, conveniently located on left side of our website.  Or, mail your donation to: Friends of the OCCSB at P/O Box 1512 Ontario, CA 91762.  Your donation helps to keep music alive in the community!

We look forward to seeing you at one, or all, of our programs this year.  Please be sure to check our show schedule for our performance and venue calendar.  As always, thank you very much for your support of the Ontario Chaffey Community Show Band... THE GREATEST SHOW BAND IN ALL THE LAND!!
