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
