2 Sisters On Enjoying Life: Instead Of 'A Drama Or A Novela, Make It A Sitcom' Sisters Corina Ulloa and Brenda Ulloa Martinez grew up in the Boyle Heights neighborhood of Los Angeles. Brenda, 46, and Corina, 44, passed on their own childhood memories to Brenda's young daughters, Isabela and Camila, in an interview with StoryCorps in 2010. Their parents came to the United States from Mexico when they were in their 20s. Irma and Arnulfo Ulloa each worked full-time jobs when their children were young. Before opening a bridal shop together, Irma was a seamstress in a factory, and Arnulfo was a delivery truck driver. As a result, their daughters had to commute to elementary school by themselves.
