Mrs. Diana Costello

I have been a teacher since 1998 and love my job! I am passionate about writing and enjoy teaching students how to be creative, responsible and kind while having fun getting it all done. I feel that it takes teamwork in order to make a community successful. 

I am a resident of Livermore and have a sophomore this year at Granada High School.

Looking forward to a terrific third grade year!

Mrs. Costello
