Bernadette John holds a master of music in music performance from Austin Peay State University, where she studied with Dr. Spencer Prewitt. At APSU, John co-founded The Fiddlin' Peayple, the on-campus folk music ensemble. She also holds a bachelor of music in music performance as well as a bachelor of science in business administration from Bowling Green State University, where she studied clarinet with Kevin Schempf and Georg Klaas.

In 2022, John was invited to perform as a Rising Artist at the International Clarinet Association's (ICA) 2022 ClarinetFest in Reno, Nevada. This performance included a presentation of two lesser-known clarinet works by Irish composers.

The group recently performed a recital at the International Double Reed Society's annual conference, bringing a program centered on nature in a celebration of music for reed quintet. 

In her free time, John enjoys Irish and American fiddling, singing seán-nos and studying the Irish language, photography, and rambling around the great outdoors.
