Burleson and the rest of Johnson County are covered by the North Central Texas Council of Governments (NCTCOG) Area Agency on Aging, not the Tarrant County agency -- reach NCTCOG at 800-272-3921.
What is specific to this county
This is a genuinely easy mistake to make, since Burleson sits directly adjacent to south Fort Worth and functionally feels like part of the same metro. But the county line matters administratively here: Johnson County falls under NCTCOG's 16-county Area Agency on Aging region rather than Tarrant County's separate, standalone agency. NCTCOG's Area Agency on Aging office is physically located in Arlington (616 Six Flags Drive), which can add to the confusion, since Arlington itself is in Tarrant County and served by the Tarrant County agency -- the NCTCOG office simply happens to be headquartered there while serving a different, broader set of counties.
