What is specific to this county
Tarrant County's arrangement is worth understanding on its own, since it differs from how most of the surrounding North Texas counties are organized. Rather than falling under the larger 16-county North Central Texas Council of Governments (NCTCOG) region the way Parker, Johnson, Denton and Wise counties do, Tarrant County operates its own dedicated Area Agency on Aging, administered through United Way of Tarrant County rather than a council-of-governments structure. This includes its own Long-Term Care Ombudsman Program as well. If you're calling for help anywhere inside Tarrant County's borders, this is the office to reach first.
