Hello and welcome to my page. This is my 6th year teaching at Wylie ISD. I am originally from San Antonio, Texas (Go Spurs Go). I moved to the Dallas area to attend The University of Texas at Dallas, where I received my undergraduate degree in Neuroscience. I also have my master's degree in Biological Sciences through Texas A&M Commerce. I am married to my amazing husband, Ethan, and have one daughter, Ellie. 


When I am not teaching, I am likely outdoors exploring nature with my family, shopping at Target, or picking up some Starbucks!
