Rosie Rivas

Assistant Director

Rosie has worked with kids for 14 years, and has taught at the preschool since 1996. Rosie says, “I like working with kids because I love children. For me, being a childhood educator is a gift that I have received from God. When I am working with a child, it gives me the privilege to be a part of their academic and spiritual growth. Another reason I like working with kids is that while they learn from me, I learn from them. I think it is awesome how honest they are. They will tell you straight out things that sometimes you don’t want to hear, like ‘do you have a baby in your tummy?’. Finally, I don’t just like working with kids, I enjoy it greatly.”

Her favorite verse is Philippians 4:13, “I can do everything through Him who gives me strength.”


1 Peter 3:15 “but in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you: yet do it with gentleness and respect,”
