His father, Reuven Heifetz, was a local violin teacher and served as the concertmaster of the Vilnius Theatre Orchestra for one season before the theatre closed down. Heifetz and his family left Russia in 1917, traveling by rail to the Russian far east and then by ship to the United States, arriving in San Francisco.
He became a naturalized American citizen in 1924.
