About Us

The Rose City Sing-Off is filing for a 501C3 Non-Profit dedicated to providing a premier forum for High School a cappella programs in the Pacific Northwest.

This event is meant to provide education and entertainment to our all of our participants and families. I would like to thank all the hard working committee members that have helped to program this year’s Rose City Sing-Off!
