Katty Rosenstock

Katty Rosenstock was born in 1956 in San Jose, Costa Rica. Both of her parents came to Costa Rica as teenagers, following grandparents who had emigrated from Poland. Her father's family came from a small shtetl near Warsaw, and her mother's family came from Lukow, a somewhat larger town. Facing rising antisemitism and severe poverty, her paternal grandfather Dov (last name transcribed as Rochwerger) was among the earliest of the 1930s wave of Jews to reach Costa Rica, arriving through the Caribbean port of Limon. He married Sarah, who kept a kosher house that welcomed many newly arrived men. A winning Panamanian lottery ticket allowed her father's family to bring everyone over at once, while her mother's family, bringing relatives one at a time, lost two of her mother's sisters and their families in the Holocaust, including an uncle who was a shochet.

Katty grew up immersed in Costa Rica's small but vibrant Jewish community, attending a Jewish school from preschool through high school and graduating in one of its earliest classes. She met her future husband, Julio Rosenstock, through a Zionist youth scouting group where he was a leader; he had traveled to Israel during the Six-Day War. They married in 1975 and spent a year in a coffee town, San Marcos de Tarrazu, for Julio's required social service. The couple later received scholarships to study in London, where Katty earned a master's degree in population studies through the World Health Organization and Julio trained in endocrinology.

About 40 years before the interview, the family moved to Dallas when Julio joined UT Southwestern, joining his brother David, a rheumatologist, who already lived there. Their daughter Javi was born in Dallas, and the family enrolled their children at Solomon Schechter, then in Sherith Israel, where Katty felt immediately welcomed among a community of fellow immigrant families. Katty's oldest brother Henry died young after polio, and she has a sister, Susie, and a brother, Benny, an engineer living in Israel. Devoted to family, Katty gathers her children and grandchildren, and made memorable journeys back to Poland, including one with the March of the Living, to visit her ancestral towns and honor her family's history. She treasures both her Jewish and Latin American roots and considers Dallas, like Costa Rica before it, a warm and welcoming home.
