Coronavirus Updates
Normal life looks a lot different these days, especially in healthcare. But there is one thing that hasn’t changed at Children’s Colorado: Your child’s health and safety are our highest priority. Kids need great pediatric care as much now as ever, and it’s for that reason that we’re reactivating services we temporarily suspended due to the pandemic. We are here to deliver safe, thoughtful, high-quality care for kids who need it. Learn what to expect – and all the ways we’re keeping patients safe.
For ongoing updates, a list of open locations and how to get care virtually or in person, please see our coronavirus resources for parents and resources for healthcare professionals. For questions about visiting our locations, such as face covering requirements, inpatient visitation and outpatient appointments, please see our visitation policies.

In life-threatening emergencies, find the emergency room location nearest you. For non-life-threatening medical needs when your pediatrician is unavailable, visit one of our urgent care locations.

Provider of the Month - Children's Hospital Colorado 2018
This initiative celebrates members of our Faculty Medical Staff each month for their accomplishments. Your recognition comes from your commitment to the quality and safety of all those within the institution: “Thank you for being such an advocate for our patients and OR team on shift last week. We have policies in place for a reason and it was very appreciated that you held your ground in supporting them. It made for a safer work environment for the rest of the team members and had a trauma arrived, we would have been in a much better position to provide patient care. You rock, thank you!” -Medical Staff Services
