Ms. Sydney grew up in Boerne and the surrounding San Antonio Hill Country, earned a bachelor’s degree in psychology from Auburn University, and pursued law school in Knoxville, Tennessee, before finding her fit here at HCMS. Ms. Sydney also has a background in behavior therapy and has a passion working with children of all ages.

When she’s not working, Ms. Sydney enjoys being active, spending time with friends and family, gaming on her Nintendo Switch, and watching college football — WAR EAGLE!
