But Mateo felt the action was a success: They had shone a spotlight on a critical issue and reunited six young people who had grown up in the United States with their families; since then, none has been deported, and one has been granted asylum. A judge administratively closed Mateo’s own immigration case a year later.
“The experience left me feeling guilty: I had done something that people thought was crazy and was allowed to stay here,” she said. “But the other women detained at Eloy couldn’t do the same thing.”

Just six days after her release, Mateo started law school at Santa Clara University. Culture shock hit her, as classmates stopped to ask, “Wait, are you that girl?” She struggled with guilt about not being able to actively help less privileged immigrants and a sense of not belonging in the competitive environment. Mateo thought about leaving, but a pep talk from her contracts professor, Michelle Oberman, reminded her of why she was there: This was her dream, and she could use it to help others.
“Mateo is the single most collaborative yet inspirational student I’ve ever taught,” Oberman recalls. “It’s like she leads from within, not in front or behind—there’s a sense of moral centeredness.”
Mateo spent summers clerking at the Legal Aid Foundation of Los Angeles, where she helped survivors of domestic violence with their immigration cases, and California Rural Legal Assistance, where she supported impact litigation efforts. During her 3L year, she represented clients in workers’ rights cases at the Katharine & George Alexander Community Law Center, where she remains a volunteer. These experiences cemented a desire to work in direct service.
After Mateo graduated, she fell ill with thoracic outlet syndrome, a condition in which pinched nerves caused excruciating pain. After four months recuperating, she took the bar and then started working for Pasadenans Organizing for Progress, a local social justice organization. When she passed the exam in May 2017, she asked de León, the senator who would eventually appoint her to the state advisory committee, to swear her in.
