From the Principal
DR. SEVERIN CORNELIUS
With nearly 30 years of experience in the field of education, I have dedicated my career to fostering student success, empowering educators, and advancing school communities through effective leadership. I hold a Doctorate in Educational Leadership and Organizational Innovation from Marymount University, where I deepened my commitment to creating impactful, forward-thinking educational environments.
Since 2005, I have proudly served as an administrator in the Mount Vernon City School District. Throughout my tenure, I have worked collaboratively with students, families, teachers, and fellow leaders to improve academic achievement, promote equity, and support continuous improvement across schools. My leadership philosophy centers on building strong relationships, maintaining high expectations, and driving innovation that prepares students for lifelong learning and success.
Welcome Back Letter 2025-2026
Greetings, Grimes Families,
Welcome back to a new and exciting school year! We hope your summer was filled with rest, joy, and quality time with loved ones. As we begin this new chapter together, we are thrilled to partner with you in supporting your child’s academic success and overall growth.
At Grimes School, we believe every student has the potential to thrive and achieve excellence. Our dedicated teachers and staff are committed to providing a safe, engaging, and challenging learning environment that fosters critical thinking, creativity, and a lifelong love of learning.
This year, we are placing a strong emphasis on academic achievement and excellent school attendance. Research shows that students who attend school regularly perform better academically and are more likely to graduate ready for college and career opportunities. Everyday counts—when students miss school, they miss valuable instruction and the chance to connect with peers and teachers.
We kindly ask for your support in helping your child arrive on time and ready to learn each day. Establishing consistent routines at home—such as early bedtimes, organized school supplies, and limited screen time—can make a big difference in your child’s success. Together, we can build strong habits that set the foundation for a productive and rewarding school year.
Please know that our doors are always open. We value your involvement and encourage open communication between home and school. Let’s work together to ensure that this year is one of outstanding growth, learning, and achievement for every student.
Welcome back, we can’t wait to see what this school year will bring!
