Our ESOC address 911 Tracy Chambers Lane, is dedicated to Tracy Chambers who was a long time Williamson County EMS paramedic that retired in 2010. She moved to west Texas in 2010 where she worked for a fixed medical transport agency. On July 4, 2010 while transporting a patient, the plane crashed on liftoff and our team lost someone who made such an impact on her Williamson County employees and residents. Tracy provided outstanding care and customer service to Williamson County residents for over 2 decades and she will be forever missed.
