    Sylvester Students, Families and Community,

    It is with great excitement that I will begin this upcoming school year as the principal of Sylvester Middle School. I have come to know that Sylvester is a special place and that its staff, students and families have a genuine affection for the school and for one another. I have already had the opportunity to meet with all of the staff, many students, members of the PTSA, and parents and am grateful for their warm reception. It is also exciting to join Sylvester’s diverse community of learners and the stakeholders committed to supporting them.

    I have been a member of the Highline family since 2009 serving as a math teacher for four years, two years as dean, and for the last two years as assistant principal at Chinook Middle School. In my years of experience in the Highline School District I have had the privilege to collaborate and learn with many dedicated educator and administrators. My dedication to work in Highline can be characterized as a response to a calling. I have lived in and around the Highline area for twenty years and am proud to call this community my home.

    As your new principal I will be leading with the district’s promise to know every student by name, strength and need so they graduate ready for college, career, and citizenship. The work in progress of the Sylvester school community to deliver effective instruction will be continued by the new administration. It is our goal to increase access to core curriculum, and opportunities for students to affirm and develop their strengths as independent learners in a safe and civil environment. The instructional program will be supported by developing staff to deepen the roots of established academic and social-emotional systems of support and by examining all practices through the lens of equity and social justice.

    Please know it is an honor and a privilege to serve the “Tomcat Nation” and to partner with the many stakeholders who will be engaged in ensuring achievement for all students through excellence.  My door is always open and you are welcomed and encouraged to call

    206 631-6000 or email gilbert.parsons@highlineschools.org as needed.
