Andrew Taylor, Band Teacher
Andrew Taylor grew up in Australia playing Jazz Big Band music with his Mum. He gained a Bachelor of Music, and a Bachelor of Drama, from the University of New England (the Aussie one). He then re energized the Young Regional School of Music, a regional conservatorium in the Aussie Bush, from four private students in 1994 to over 500 students in five towns and 15 schools by 1997, a growth that was rewarded by the government with an Australia Day Cultural Medal.

Andrew then traveled to teach music in schools on Kangaroo Island, in Vietnam, Turkey, Romania, and then Washington DC for many years, where he taught at Capitol Hill Day School and Alexandria Country Day School. This gave him the opportunity to work with the National Symphony Orchestras of these countries, bringing professional musicians from these ensembles into his schools each week to give instrumental lessons to school students. While on his travels, Andrew was able to complete an Honors in Musicology at the University of Adelaide and an MA in International Education at the Westminster Institute of Education at Oxford Brookes University in the U.K. He plays Trombone, Trumpet, Sax, Bass Guitar, and a little Flute (but not the piccolo, though...). Andrew’s wife is from Sacramento and they met in Turkey, of course. She brought his Aussie cat with her from Turkey to Sacramento, and now they have 4 cats to herd and wrangle in the beautiful California sunshine.
