Mrs. Stephanie Costello

My name is Stephanie Costello and I have been teaching kindergarten at BWE since 2015! Before coming to Brennan Woods, I taught kindergarten at Bowles Elementary. I was also a classroom assistant for Rockwood Early Childhood.  

I am so excited to be your child's teacher! I am looking forward to helping your children grow and learn this year! I value a partnership between school and home and I believe the best way to achieve this is through open communication. Please feel free to contact me any time through email, phone, or notes!
