HMS Families,

Welcome to the 2021-2022 school year!  We are excited for a great school year with all of our T-Birds!  This will be my sixth year at Harmony Middle School, and third year as Principal.  Prior to being principal, I spent three years as the assistant principal and have loved every moment of my time at HMS.  We have such a wonderful school community that is supportive, caring, and positive.  I am honored, excited, and proud to serve as principal here at HMS.  Previous to entering administration, I taught high school social studies at both Blue Valley West and Blue Valley Southwest High Schools and coached boys' basketball and boys' and girls' golf.  I truly enjoy working with students inside and outside of the classroom and I am looking forward to providing your child with a great middle school experience.


I received my B.S. in Education from Rockhurst University and my Master's in School Administration from the University of Texas at Arlington.  When I am not at HMS, I enjoy spending time with my wife Florence and our three kids Natalia, Andres, and Camila.  We enjoy being active and doing fun things together as a family.


I truly believe we offer the total package at HMS.  We have an outstanding staff that care deeply about our students both inside and outside of the classroom.  We look forward to providing an exemplary academic program and enriching extra-curricular activities to give our students the best middle school experience. 

Proud Principal,
Nate Winslow
