    Hello! My Name is Mrs. Sarah O’Brien and I am so excited to be your child’s second grade teacher this year. This will be my ninth year of teaching and my fourth year in Allen. I have been married to my husband, Sean, for four years now and we have a 2.5 year old daughter named Harper and will welcome our little boy into the family in August 2022.  On the weekends we love to play outside, go to the pool or explore fun new places.  I’m looking forward to getting to know your child and watching them grow! Please feel free to contact me with any questions or concerns. Together we can make this the best year!
