Memorial Hermann Katy ER - A Level III Trauma Center

Memorial Hermann Katy Hospital is a designated Level III Trauma Center with the ability to provide advanced trauma life support, evaluation, stabilization and diagnostic services.

Having an integrated and comprehensive network of trauma centers allows Memorial Hermann staff throughout the city to work in unison, no matter the location or needs of a patient. At any Memorial Hermann Emergency Room, a patient benefits from the knowledge of a large network of physicians and nurses trained in emergency medicine as well as the years of experience Memorial Hermann has accumulated as Houston’s emergency care leader.
