Greetings 500 Building Families,

It is with great pleasure that I join Collegium’s 500 Building as your new Principal. I am very excited to embark on this journey to lead 500 “Cougars” to success.

I am aware that this school year has presented many challenges, likewise, historically that has been the case across the country due to extenuating issues surrounding the effects of COVID19. I want to assure you that I will work collaboratively with all stakeholders to address Collegium’s most pressing needs.

I come to you with over 18 years of experience in education. Seven of those years have been in educational leadership in various roles. Most recently I have served as Assistant Principal for the School District of Philadelphia and was a member of the Aspiring Principals Academy. A critical part of my leadership work has been spent developing effective teachers. I firmly believe that one of the keys to a successful school lies in the hands of effective teachers. Therefore, through the collective leadership of Assistant Principal Moore and Assistant Principal Miller, we will ensure every classroom is equipped with high-quality instruction and optimal learning opportunities. We will work hard to make sure all the Collegium scholars have the recipe they need to achieve at high levels.

It is my expectation that every child who walks through our doors feels welcomed, supported, and academically challenged. The dedicated Collegium staff will continue working hard to implement systems to provide a safe and nurturing school community that supports the academic and social-emotional needs of your child.

I welcome your partnership in helping make this school year amazing and look forward to providing your child with the best learning experiences possible. Thank you in advance for all that you do to make our experiences positive.

With Sincere Gratitude and Appreciation,

Myishing A. Cox, M.A.Ed
