No Wait Emergency Room


ER Katy is a free-standing, state-of-the-art emergency room conveniently located in the heart of Katy, Texas. We’re dedicated to serving our community, and caring for the emergency needs of our neighbors.

Emergencies can strike at any time, day or night, so we’re open 24 hours a day, 7 days a week. Our doctors are Board Certified in Emergency Medicine and have completed advanced clinical training and education in the specialty area of emergency medicine. Along with our dedicated healthcare support staff, we are able to offer the best emergency medicine treatment options available with little to no wait time.

Because our doctors are Board Certified in Emergency Medicine, this means they have undergone extensive education, training, and a rigorous review through board examination.
