Brett Hosterman is a life-long resident of the Susquehanna Valley. After finishing his degree in music education from Susquehanna University, Hosterman was hired by the Milton Area School District where he served as the director of instrumental music. At Milton, his teaching responsibilities included grades 6-12 instrumental music, marching band, jazz band, eight-grade general music, and high school electives in music theory and appreciation. In 2011, Hosterman founded and still conducts the Milton Area Community Band, which boasts over 80 active members ages 15-92.
Throughout his professional teaching career, Hosterman was actively involved in the Pennsylvania Music Educators Association, having served as District 8 president, vice president, band festival coordinator, and sat on various state-wide committees.
In 2015, Hosterman left the teaching profession to explore his other interests in the arts, ultimately opening his own business "Hosterman Creative." His business allows him to mix his other passions of photography and graphic design with his love of music and the arts. In addition, Hosterman serves as organist and music director at First Baptist Church of Lewisburg, Pennsylvania, and is a sought-after guest clinician, pianist/organist and conductor throughout the commonwealth.
