Mr. Dennis Garza

I have been an educator for 20 years.  I started my career in Houston at North Shore High School 9-10 in 2001.  I came back to Southwest High School, where I taught from 2003-2005.  Since 2005, I joined Harlandale ISD as a World Civilizations teacher at Harlandale Middle School.  I then became an administrator in 2018.  I served as a Vice Principal for Discipline for three years, before moving over to McCollum High School this year.  I bring with me many years of service as an educator and look forward to serving the Harlandale community south of Military Drive.
