Our History

In the 1950s, parishioners from Holy Rosary Church began broadcasting the recitation of the Rosary on Portland commercial radio. This would eventually lead to our station’s inaugural KBVM broadcast on December 8, 1989, from our studios at the University of Portland! This also marked the first time a US Catholic radio station was purchased by the laity and supported by its listeners.

On December 20, 2011, Catholic Broadcasting Northwest, Inc. started broadcasting in the south end of the Willamette Valley with with our KMME broadcast in Cottage Grove and Eugene, Oregon.

The Summer of 2019 marked a historic moment for the station, as we moved into our very own media center in Southwest Portland.

In 2021, we launched our Hail Mary Media app as part of many digital initiatives to continue the work of the new evangelization.
