Alexandra “Sasha” Fox

Alexandra “Sasha” Fox was born in Kishinev, Moldova. With the intent of immigrating to the United States, her family lived in Israel and France in the 1970′s, finally settling in Borough Park, Brooklyn.

After graduating from the University of Hartford, she landed a job at Salomon Brothers working in Compliance; she then made her way into Sales and Trading in various roles on the trading floor. Her career turned to Client Management, working as a strategic partner within Equities to help US and Global managers implement initiatives that helped increase revenues and productivity. As the firm evolved into Salomon Smith Barney, and then eventually, into Citigroup, Alexandra left the firm after 15 years of service to work at JP Morgan. She helped establish its Client Management department and worked with Sales through the Bear Stearns merger.

After four years at JP Morgan, a lucrative position became available to start up Client Management for Global Equities at Jefferies & Co where she implemented significant business, infrastructure, and technological initiatives. As the political and financial landscape changed in the past few years, Alexandra is taking time to concentrate on her family life. She just recently moved with her husband and two young sons to New Rochelle, NY.

Alexandra attended Jewish elementary and middle schools (Shulamith and Bialik in Brooklyn); however, her family was not observant. After September 11, 2001, she met her husband, Andrew, through Aish HaTorah and as they became more involved with the Upper West Side Jewish community, they began to live a Modern Orthodox lifestyle. In 2012, they were honored at the West Side Institutional Synagogue 91st Annual Dinner for their service to the community. They support various Jewish organizations in the US and Israel.
