Founded by friendship the choir was conceived in the minds of sisters Ana, Rita, and Cielo Bansuli together with their neighbor, sisters Melvic and Marivic Matalang. The group was created 17th of August 1987 when a group of seminarians from St. Vincent had their apostolate together with the image of Our Lady of Miraculous Medal (name of Medallion was taken) at Metro Heights, Visayas Ave. Culiat, Q
uezon City and a choir was needed for the mass. The group started singing acapella during eucharistic celebrations and also singing at San Lorenzo Ruiz Parish every saturday evening mass. From 1988 to 1989, another group of seminarians, which is the Franciscans, lived in the community for more than a year and help the group in singing. In 1989, the Augustinians had their apostolate and both congregations accompanied the group in singing during masses. Sometimes they hold their practices at the seminary. Then in the year 1992, the Medallion Choir became part of the music ministry of Parish of the Mary the Immaculate Conception, under the guidance of Bro. Dalmacio Eusebio (Parish Priest). At present, the group consist of members from Metro Manila and the choir is still growing and continuing the mission.
