During the late 1940s and 1950s, he performed at venues in the Philadelphia area. In the mid-1950s, he moved to New York City and recorded with Charlie Ventura and Red Callender, and in 1958 he moved to Los Angeles to record for Decca. In Los Angeles, he worked with Buddy Collette, Paul Horn, John Pisano, Bud Shank, Milt Bernhart, Les Elgart, Herb Geller, Lorraine Geller, Calvin Jackson, and Zoot Sims.
