    Hello! My Name is Mrs. Sarah O’Brien and I am super excited to be your child’s fourth grade teacher this year. This will be my sixth year of teaching but my first year in Allen. I have been married to my husband, Sean, for a year now and we are expecting our first child, Harper, in November! We have two dogs and one cat. I’m looking forward to getting to know your child and making this their best year yet!
