HSIs represent less than 20% of all institutions in the U.S., however, they enroll over two-thirds of all Latino students attending post-graduate studies. The purpose of the study was to expand the research on how institutional practices and ecosystems grounded in white normative values marginalize the lived experiences of Latina students at Hispanic Serving Institutions (HSIs). The main topics related to the research questions that guided the study was culturally sustainable pedagogy, culturally engaging campus environments, and third spaces, as well as how Latinas continue to make sense of their ethnic consciousness identity and community cultural wealth assets. Employing "Testimonio" as a methodology situated the researcher in the dialogue with the participant to offer a voice for the marginalized and introduce the counterstories of Latinas navigating experiences of marginalization. The purposive sampling technique was employed to ensure a diverse sample of Latina voices by ethnic identity and broad expression of experiences and perspectives. Eight participants that self-identify as Latina attending an HSI participated. The procedure used to analyze the data consisted of a shared data analysis process of knowledge production incorporated throughout the interview process with the participants to identify emerging themes for the analytic process and allowed for co-construction of knowledge between the participants and researcher. The conceptual frameworks utilized to guide the study are grounded on empirical research of Latina/o students' experiences such as Latino Ethnic Consciousness and the Community Cultural Wealth Model. Overall themes that were most salient on how Latina students experience pedagogy, classroom environments, third spaces, and make sense of their ethnic consciousness identity and cultural wealth involved unconventional learning environments, affirmation of community cultural wealth, imposter syndrome, sense of familismo, and academic acculturation.
