Welcome to Mrs. O'Brien's Pre-K classroom! My name is Karen O'Brien. I live here in New Caney with my family. I graduated from the University of Houston - Clear Lake in 1992. I have been teaching since 1993 and have taught Pre-K and Kindergarten before coming to Crippen Elementary. This is my 5th year here at Crippen. I am very excited to have your student in my classroom.
