Yoseli Castillo is originally from Guatemala, and began her training in education by participating in the Child Development Associate (CDA) program, where she gained the knowledge and skills to support the holistic development of young children.

As part of her professional preparation, Yoseli joined the All Five for her practicum; this experience allowed her to work directly with children, observe various teaching strategies, and strengthen her skills as a future educator.

Yoseli is the mother of two children, aged 6 and 12 — an experience that has deepened her understanding of children's needs and the importance of collaboration between school and families. In her free time, Yoseli enjoy walking, exploring new places, and trying different foods, as she loves learning about diverse cultures.
