Schertz is a city in Guadalupe, Bexar, and Comal Counties, Texas, on the Interstate 35 corridor northeast of San Antonio. It is part of the San Antonio metropolitan area and sits adjacent to Randolph Air Force Base, now a component of Joint Base San Antonio. That location — between San Antonio and New Braunfels, along one of Texas's fastest-growing corridors — has defined Schertz's rise from a small German-settled community into one of the region's largest and fastest-growing suburbs, with a population now around 45,000. The community's roots are German-Texan, part of the broader Central Texas settlement pattern, and it remained a modest town for most of its history. The arrival of Randolph Field in the late 1920s, when land near Schertz was transferred to the federal government for a flying training base, established a long-running military presence that continues through Joint Base San Antonio. Schertz's growth accelerated sharply in the late 20th and early 21st centuries, with its population nearly doubling between 2000 and 2015 as San Antonio expanded northeastward. Today Schertz is a family-oriented suburban city with a strong military and commuter population. The Schertz-Cibolo-Universal City Independent School District, based in the city and serving about 15,000 students, is a central draw, and the city's parks, community pools, and newer master-planned neighborhoods support a suburban quality of life. Local employment is anchored by the military installation, retail, and commuting ties to San Antonio. For homebuyers, Schertz offers newer single-family housing, strong schools, and convenient access to both San Antonio and New Braunfels along I-35. It appeals to military families, professionals, and anyone seeking an established suburban community on the northeastern edge of the San Antonio metro.
