Welcome to the Hemophilia and Thrombosis Center at the University of Colorado Anschutz Medical Campus. Our center has undergone a variety of transformations over the years and we moved to our current location in 2011.
Our affiliation with Children’s Hospital Colorado allows us to bring the best care and expertise to all who live with bleeding or clotting disorders, including those who have survived pediatric stroke.
We hope you are able to use this website as a tool to find answers and learn more about bleeding and clotting disorders. Our goal is to work with all our patients and their families to empower them with education and strategies to overcome the challenges
they may face.
