This is the Texas A&M AgriLife Extension Service website for Grayson County Texas. We are located North of Dallas on the Oklahoma border. Grayson County has a population of approximately 120,000 persons. Sherman is the county seat and Sherman and Denison are the two largest cities, both of which are located just off highway 75. There are 13 independent school districts and several private and charter schools.
The Grayson County border is marked with the Red River and beautiful Lake Texoma separating us from Oklahoma.
Grayson County is bordered by Collin and Denton County to the South, Cooke County to the West, and Fannin County to the East. Major highways include Highway 75, Highway 289 and Highway 377, running north south. Highway 82 and Highway 56 run east west.
Our office is located in the Courthouse on the square in downtown Sherman. Enter the courthouse from the south side (Lamar Street) and we are the first office on the right.
This is also the home to the 4-H Program in Grayson County. We have community clubs in Collinsville, Sherman, Whitewright, Tioga and the Van Alstyne area as well as project clubs such as Horse (Rangers), Animal Science/Livestock, Shotgun and Animal Angels Vet Science.
