"Few careers are more rewarding than education. However, today public education faces major challenges. So called reformers, privatizers and profiteers from all sides of the political spectrum approach public schools as profit making opportunities and not as the education institutions that our students and communities depend on.""As a teacher, I must be a role model for my students and advocate for public education and educators in the community and the public arena. It’s the only way to ensure that the promise of public education for future generations is fulfilled."
