Oregon Interscholastic Snowboard Association
The Oregon Interscholastic Snowboard Association (OISA) is a 501c3 not for profit organization that provides competitive snowboarding and is committed to the development of high school snowboarders of all levels in the state of Oregon (and Southwest Washington). A combination of coached team development and competitive events work to build individual achievement in an inclusive atmosphere that fosters long lasting bonds with teammates and other competitors. With a dedication to coaching excellence, a focus on safety, and an insistence that everybody has fun, OISA events are a highlight of the winter for many of our student athletes.
