Amy Andrade

Maple Program Coordinator

Amy Andrade joined JOYA Scholars in the fall of 2018 as the inaugural Maple Community Intern. Amy offered direct support to our first Maple middle school and high school students and families, and in doing so rooted what has now grown to become JOYA’s Maple college readiness family.

Amy graduated from Cal State Fullerton with a Bachelor of Arts in Human Services. As a student, she followed her passion for helping others, and joined the Human Services Student Association to further immerse herself in the heart of volunteerism and engagement that enriches our local Fullerton community. Amy also became a mentor to help her undergraduate peers reach their academic goals.

Amy was born and raised in Los Angeles County, and, with help from her local college readiness program, came to attend and graduate college as a first-generation student. Now, Amy takes pride in helping her Maple students strive for success.
