Mrs. Michelle Sell


 As an educator in Caesar Rodney School District for twenty-one years, I am very excited to serve as Assistant Principal of Postlethwait Middle School. I have had the pleasure of being pivotal in helping Postlethwait thrive, progress , and receive numerous accolades during my tenure here, and I look forward to the opportunity to take a more significant role in its continued success.

I firmly believe that all students are capable of learning and achieving at high levels within a caring, collaborative, and positive school culture regardless of their disabilities or socio-economic background. I am committed to ensuring that this vision of learning at Postlethwait is upheld, and that the supportive culture of the school is valued and protected. A proud graduate of Caesar Rodney schools and life-long Rider, I am fully dedicated to the Caesar Rodney tradition of excellence; however, I am also excited to help direct Postlethwait through the new challenges on the horizon such as the introduction of language immersion students, the expansion of distance learning classes, the evolution of the Outdoor Classroom, and the utilization of technology to enhance and adapt instruction. I look forward to making a positive impact on the students, staff, and community that Postlethwait serves everyday.
