24/7 Emergency Services in Houston, TX 77070 for Adults and Children
An emergency does not wait for office hours, and neither does NorthStar Emergency Center. Our freestanding emergency room on Cypresswood Drive is open 24 hours a day, seven days a week for adults, children and infants with sudden illnesses, injuries and potentially serious symptoms.
Our emergency physicians have access to on-site digital X-ray, CT scanning, bedside ultrasound, EKG and laboratory testing. That means evaluation, diagnostic testing and initial treatment can often happen in one location during the same visit.
