Grayson has an elementary school, but high school students attend the nearby Caldwell Parish High School in the parish seat of Columbia. Across from the elementary school and the Grayson Town Hall is Grayson United Methodist Church, with pastor Dorothy Smith (2012). The Grayson Baptist Church is just west of U.S. Highway 165; its current pastor is Rick Crandell (2012).
Grayson is also home to Conquest Tattoo, owned and operated by Manny Cavazos. In business for 5 years and counting, it is a staple for quality art in the village. Conquest Tattoo is located at 5370 Hwy 126 West
