Dr. Mary McAllister-Parsons, Principal

August 2022

Welcome Back to the 2022-2023 school year.  It is truly an honor and privilege to continue to serve the Twinhill community as your principal.  I am so very pleased that you are part of our amazing learning community. I welcome you and value your dedication to excellence in education, and I look forward to working with you and your children as a partner in education. 

Along with our teachers and support staff, I am committed to working closely with our families to provide a safe, supportive and welcoming learning environment and the best education for all Twinhill students.  We will continue to build strong relationships with parents and families, students and community partners.  We will focus on character education, Common Core standards, the use of data to drive instruction, and to provide consistent implementation of the curriculum so we can continue to increase student achievement.

Student Placement-a great deal of time, effort and thought has gone into the process of student placement.  Classrooms are balanced academically and socially and are structured to provide equitable class sizes at each grade level.  Moving students is difficult without causing imbalances and inequities.  Thank you for being positive with your child and helping him/her acclimate to their new grade, peer group and teacher.  Our staff works hard to make school a positive experience for ALL students, and we are eagerly looking forward to enriching your child’s life.

Twinhill Parent-Student Handbook is found online is to provide you with helpful information on school programs, policies and procedures.  Please read the information carefully and review it as a family.  We ask that you keep it in a safe, easily accessible place so you can refer to it throughout the school year.

Please be sure to join my "Dr. McAllister-Parsons' Family Connection" on Class Dojo.  This will allow parents and families to communicate directly with me throughout the school year.  I eagerly look forward to greeting all students and their families again in person.  Together, I know we will make this school year one of growth and enrichment as we continue to Create a PATH of Excellence for ALL through Partnerships, Aspirations, Tenacity and Heart.

All the best,

Mary McAllister-Parsons, Ed.D.
