    Hello! My Name is Mrs. Sarah O’Brien and I am so excited to be your child’s fourth grade teacher this year. This will be my seventh year of teaching and my second year in Allen. I have been married to my husband, Sean, for two years now and we had our first child, Harper, in November 2019! We also have two dogs and one cat so our house is always on the move. 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!
