Glenbrook North Tri-M

Tri-M (Modern Music Masters) is a service-oriented honors society open to any sophomores, juniors, and seniors who are in an advanced ensemble group. This includes Cecilian, Chorale, Symphonic Wind Ensemble, Symphonic Orchestra, or the Glenbrook Symphony Orchestra. We raise money for underprivleged schools, offer performance opportunities for our members, and spread our love of music through Glenbrook North and the Northbrook community at large. We also have a partnership with the Northbrook Symphony Orchestra.
