Founded in 2004

The late, great Tom Miller, and Diana Jonen, founded Tri-County New Horizons Band in 2004 after learning about the New Horizons International movement that originated at Eastman School of Music in Rochester, New York. Tom taught band in the Cedarburg public schools for over 30 years, and Diana is also a certified band instructor. Tom unfortunately passed away in 2012, and he is dearly missed.

From an ad in the newspaper inviting seniors 55+ (there is no longer an age restriction) to help create a new band, there were seven members at the first rehearsal. Some had never played an instrument before, while others had dug their old school instrument out of the closet or attic.

We’ve come a long way! Karen Wachholz joined us soon after the band began to grow, and teaches the brass both during lessons and during rehearsals where she plays along. Veteran band teacher, Pam Harrison, coaches and plays with the clarinet section as well as occasionally directing, and generally keeps everyone on their toes.

Over the years, skill levels have grown and the music has become more and more fun for the band, as well as our audiences.
