About Me

Hello students and families!
Allow me to reintroduce myself, my name is Mrs. Ybarra. Over the summer I received the sacrament of marriage, and I am so blessed to begin this new journey with my family and with God.

This year marks my 8th year at St. David, and I couldn’t be more excited to continue teaching and learning alongside all of you. What was once meant to be just a stepping stone quickly became an extension of family, and now I even prepare to send my own son here.

St. David is truly home, and I’m so grateful to be on this journey with you!
