Oral history interview with Nicole Cristina Espinosa conducted by Yancy Bayoro on November 17, 2022 for the Reflections: the Las Vegas Asian American and Pacific Islander Oral History Project. In this interview, Espinosa recalls growing up in Vallejo, California as a first-generation Filipino-American. Because their parents had converted to Mormonism while still in the Philippines, Espinosa grew up surrounded by the Latter-day Saints (LDS) community, attending church every Sunday and going off to camp regularly. In their LDS community, the Espinosa family was often the only non-White family, while among the other Filipinos at school being the only Mormon among Catholics, creating a tension in their identity. Nevertheless, Espinosa had a large extended family nearby and fondly remembers spending time with them as a teenager. They talk about moving to Las Vegas, Nevada in high school because of the low cost of living and job opportunities. After graduating high school, Espinosa worked a number of jobs from TSA at the airport to retail at Urban Outfitters. Epinosa discusses their parent's experience with assimilation and the parts of Filipino culture that were left behind. Throughout the rest of the interview, Espinosa talks about a range of other topics such as public transportation, finding good food, and their AAPI identity.
