Sergio Hamerslag (clarinet/Eb clarinet) first came into contact with the clarinet at age 11, and was immediately hooked. Thanks to a recruitment drive at his primary school by the local harmony orchestra, he started taking lessons with Gerrit de Weerd, and four years later found himself in the young talent class of the Conservatorium van Amsterdam under the tutelage of Herman Braune. During his studies he participated in masterclasses and workshops with artists such as Karl Leister, Richard Stolzman, Ralph Manno and Sabine Meyer. Eight years later he received his Master of Music cum laude under the  guidance of Herman de Boer.

Having built up a great deal of experience playing in various youth and professional orchestras both at home and abroad, he won the position of bass clarinettist at the Radio Filharmonisch Orkest in 2009.

Sergio lives with his girlfriend and three cats in Hilversum. When not playing the clarinet, most of his time is devoted to renovating his house, leading his colleagues to crown him with the nickname “King of DIY”. Sergio is also a fan of running and skiing and has had a place in his heart for trains his whole life.
