While continuing its partnership with Doctors Hospital at White Rock Lake, MedPost is part of a new and growing national network of urgent care centers launched by Tenet Healthcare to provide high-quality, efficient and convenient health services. The MedPost network currently consists of 23 urgent care centers in eight states. The walk-in centers are open seven days a week with extended hours to provide high quality care for residents in their communities. No appointments are necessary and patients are seen quickly on a first-come, first-serve basis – without a long wait.
