Jerry Feldman

Jerry Feldman, a devoted father, husband, grandfather, and charismatic entrepreneur with several successful careers…

died peacefully on September 4, 2016, with his family at his side. Jerry was 75 years old.


Born in Poland on December 26, 1940, Jerry and his mother fled from the Nazis along the Eastern Front through Poland and Russia with his aunt and cousin. Once, near starving, the two mothers left the infants in a train car to find food and returned to discover that the train had left the station. The frantic mothers ran along the tracks and found their children, still hidden, at the next station.


After the war, in 1946, with no home to which they could return, Jerry and his mother entered the displaced persons camp run by the Allies for World War II refugees in Gabersee, Germany. Jerry played matchmaker for his mom when he introduced her to fellow survivor and camp baker, Nathan Grau, who would become his stepfather. The three moved to the US in 1948, settling in Brooklyn, New York. While in New York, Jerry’s parents welcomed the birth of Jerry’s brother, Bob, who currently lives in Israel.


A talented athlete, Jerry attended the University of Bridgeport in Connecticut on a 4-year basketball scholarship and went on to earn a law degree from Brooklyn College. A successful defense attorney in the 1960s, Jerry represented a number of high-profile clients including Leroy ‘Nicky’ Barnes (aka “Mr. Untouchable”). At 40, he retired from the law and moved with his wife and his four young children to a working farm in Stanfordville, New York, where his entrepreneurial spirit soon took over as he transitioned from farming to housing construction and real estate.


A brutal winter led Jerry to move the family to sunny Southern California in the late 1980s, where he became one of the first “tech” entrepreneurs with the creation of RentLine, a company that combined computer and telephone technology to electronically advertise rental vacancies in Southern California. The success of RentLine led Jerry to create CallSource, a pioneer and leader in call management services in multiple verticals, from automotive to home services. CallSource holds multiple US patents and has more than 200 employees, the majority in its Westlake Village offices.


Jerry was deeply committed to improving the lives of his customers and employees. From his experience as a child, he always admired and honored veterans of the American military. He hired numerous veterans at CallSource and also founded PrideAmerica, an organization created to help place veterans in new careers in corporate America.


Outside the office, Jerry expressed his passion for Israel through frequent visits. He actively invested in Israeli start-ups and mentored numerous entrepreneurs. Above all, Jerry was deeply devoted to his family: his wife, Rona Feldman, his four children, Carey Fried, Daniel Feldman, Jody Feldman and Lauren Rilliet, his nine grandchildren, his brother, and his entire “extended family,” which included his nephews, nieces, cousins, employees and colleagues. More than 200 attended as he was laid to rest not far from his home in Westlake Village, California.
