Patti Graetz

Artistic Director/Principal Conductor

With a music career spanning more than 30 years, Patti Graetz, has been with ProMusica Arizona since 2015, first as Assistant Conductor and Conductor of the Women in Song vocal ensemble, and now as the newly-appointed Artistic Director and Principal Conductor.  Not only is she a skilled conductor, but she is an award-winning soprano having sung leading roles with major opera companies including Houston Grand Opera and Arizona Opera.

A Valley resident since 1989, she was head of vocal departments at the Arizona Conservatory for Arts and Academics in 2003 and at the Arizona School for the Arts from 1998-2002. She was Director of Music at Shepherd of the Valley Lutheran Church in Phoenix from 1995-2004. Before that, she was Director of Music at Scottsdale Presbyterian Church. Patti attended Concordia College in Moorhead, Minnesota where she was a soloist in the world-renowned Concordia Choir under the direction of Paul J. Christiansen.

Patti lived in Australia from 2004 to 2012 where she was a featured soloist with Australian Music Events, sang numerous recitals and concerts, was vocal teacher for the Opera Scholars Australia young-artist program, and was the Conductor of the Murray Conservatorium Choir and the Murray Conservatorium Youth Choir.

She was principal soprano for professional ensembles “Opera-tunity” and the Royal Renaissance Singers starting in 1990 and sang in hundreds of performances during her 12-year tenure.  Upon her return to the US, she began singing again with the Royal Renaissance Singers during the holiday season.

She is married to Australian husband, Trevor, and has three children and three grandchildren. She teaches private voice and piano at home and recently sold her successful mobile teaching studio, The Music Bus.

You might spot Patti getting some “wind-therapy” on her Can-Am Spyder three-wheeled motorcycle, riding to rehearsals and even cross-country. In the summer of 2018, she and her husband rode – on separate bikes – almost 5,000 miles to Colorado, the Black Hills, Yellowstone and the Grand Tetons before returning home.
