I am honored to have the opportunity to join the Heritage High School family!  As I come upon my 19th year in education, I am thrilled to join such a diverse community of learners.  

I am a native of Covington, Georgia.  I received a Bachelor’s of Arts in English and a Master’s of Teaching in Secondary Education from the University of West Georgia.  I completed my Educational Doctorate in Educational Leadership at Walden University.

My teaching career began at Northgate High School in Newnan, Georgia in 2000 as an English teacher.  I then had the opportunity to serve as an English teacher, department chair and inaugural member of Dutchtown High School in Hampton, Georgia.  In 2008, I began my journey into administration as the Instructional Assistant Principal of Spalding High School in Griffin, Georgia.  From 2013 until 2019, I served as Instructional Assistant Principal at Union Grove High School in McDonough, Georgia.

I have a wonderful and loving family: husband, Juan, and two children, Avery and Ryan.
