Born in Tacoma, Washington in 1900, Needles studied at the University of San Francisco, then known as Saint Ignatius College. Needles played basketball for the then-Grey Fog, becoming a player-coach during his senior year in 1924. He was appointed the basketball team's full-time coach upon his graduation. Needles coached Saint Ignatius College to two championships, capturing the Far Western Conference championship in 1928 and the Pacific Association title in 1929.
Needles also coached Saint Ignatius' football team during this period, leading them to a runner-up spot in the 1928 Far Western Regionals.
Following the Berlin Olympics, Needles returned to the college ranks, this time at Loyola of Los Angeles, where he mentored future coaches Pete Newell, Phil Woolpert and future Loyola coach Edwin "Scotty" McDonald. He returned to the University of San Francisco in 1941 as its athletic director and was instrumental in Newell's appointment as head basketball coach in 1946.
