While at SAC, Mrs. Krause became a Boys Town Administrative Trainer, Boys Town Trainer of Trainers, was certified in Reconnecting Youth (Drug and Alcohol), Redirections (Gang, Drug, and Alcohol), and as a R.O.P.E.S. Trainer. She was also Teacher of the Year during her tenure. She then transferred to Central Elementary in Seagoville, where she worked as a teacher for many years before becoming the school’s counselor. While at Central, Mrs. Krause won Teacher of the Year, and a few years later as counselor, was voted Counselor of the Year for the entire Dallas district.

    As a 30 year resident of this community, Mrs. Krause states she is passionate about the possibilities of growing “our” city. Her goal is to assist Kleberg Elementary in becoming the very best school in the feeder pattern. She believes Kleberg is a school of learners; and not just student learners, rather one where everyone is a learner, including her. As the philosopher Martin Heidegger said, “in true education, it is always the teacher who learns the most.” Her desire is to help her school become a model environment in which all flourish and enhance society by continuing to learn, and continuing to expect the best. She believes that in most instances people are willing to do what they are asked if they are empowered to do it, and that we should enjoy being educators, deriving personal satisfaction from work. Otherwise, she says, how can we learn or teach anything?
