Momentum choir was established in the Niagara Region in 2007, through the vision of Executive and Artistic Director Mendelt D. Hoekstra, with the assistance of Bethesda Community Services and a grant from the Ontario Trillium Foundation. It is a registered charitable organization and operates under the guidance of a Board of Directors. Since its inception, Momentum has grown to include over 45 talented singers and musicians who are passionate about sharing their joy in music with the world. It has become a sought-after choir that carefully chooses the events and venues at which it will perform. Momentum rehearses weekly in St. Catharines, and all singers are invited to a placement audition.
