Dalton Mumphrey’s earliest memories are filled with the crackling sound of vinyl and the joy of family gatherings around his dad’s vintage stereo system. These moments ignited his lifelong passion for music, leading him to begin playing the flute at age ten and later study saxophone throughout high school and at the Young Lions Jazz Conservatory under the guidance of Gilbert Castellanos. His musical journey took him from his hometown of Murrieta, California, to Los Angeles in 2020, where he continued to pursue his career and education.

Currently based in Los Angeles, Mumphrey is a versatile musician, composer, and educator renowned for his dynamic performances and innovative contributions to the music scene.
