Bill Griffin is widely known as a musician in both bluegrass and Hawaiian music genres. A luthier and veteran mandolinist, he is also the inventor of the "mandolele", which is a nylon-stringed mandolin that he first crafted in 1986. Born in Glendale, California, Griffin's first exposure to music came through his father, a pianist in a Dixieland jazz band. Griffin began playing ukulele at age five, guitar soon thereafter, and mandolin at age nineteen. He also plays piano and bass.
