His father was born in Austria and fled the Nazis immigrating first to Israel and then the United States in 1951 after a stint in the British Army. His mother was born in Belgium to a Polish Jewish family who was hidden from the Nazis by a Catholic institution for six years; her entire family perished in the Holocaust. His parents met at a resort in the Catskills and settled in nearby Fleischmanns, New York; his father owned a gas station where he also worked as a mechanic and sold used cars. Pasternak received his high school diploma in 1972 from Margaretville Central School and received a B.S. degree in education from The State University of New York at New Paltz in 1977. He moved to Ridgewood, New Jersey where he renovated a home and then moved to Jersey City, New Jersey which at the time was hotbed of stock trading, an industry that he sought to enter.
