Mrs. Castello

Welcome to Kindergarten! I am excited to start this new year with all of you!  This is my 16th year in the district teaching kindergarten.  I have to say that kindergarten is my favorite grade to teach.  I graduated from CSU Hayward, which is now called CSU East Bay, with  a Bachelors Degree in Liberal Studies and  I also received by   Multiple Subject Teaching Credential from CSU Hayward.
