I am honored to serve as the principal of Collierville Middle School and am excited to welcome your family to our school community. My journey in education began in the classroom and on the field, where I taught and coached both baseball and football at Southwind High School from 2009 to 2015. These early years instilled in me a passion for student development, teamwork, and the power of strong school culture.

In 2015, I joined Collierville High School as an assistant principal, where I proudly served for six years. From 2021 to 2023, I had the opportunity to support students across the district as the Career and Technical Education (CTE) Supervisor for Collierville Schools. Most recently, I returned to Collierville High as Vice Principal, serving from 2023 to 2025 before transitioning into my current role at CMS.

Collierville is more than just the place I work—it’s the community my family calls home. My wife, a former teacher at Crosswind Elementary, currently serves as an Instructional Technology Facilitator at Tara Oaks Elementary. Together, we are raising three wonderful children—Cantley, Rue, and Caroline—all of whom are proud students at Tara Oaks.

As both an educator and a parent in Collierville Schools, I understand the importance of creating a learning environment where every student feels seen, supported, and empowered to succeed. I am committed to fostering a culture at CMS where everyone matters, and where each day is a great day to be a Dragon.

I look forward to partnering with you to ensure a successful and fulfilling school year for every student.
