ASHLEY MARTINEZ, Program Evaluator

Ashley Martinez grew up seeing the disparities between the inner city of South Los Angeles and suburban area of Pomona, California.

With this knowledge, she began her career in higher education working for federal programs like TRIO Student Support Services, serving as faculty within the Chicano Studies department at Colorado State University - Pueblo and advising first-generation students of color in pathways that led to higher education or the workforce. Returning home to Los Angeles, Ashley is excited to share her knowledge and develop relationships in the community that helped shape her as an individual.
