Hemophilia and Thrombosis Program Team

Our Multidisciplinary Team Members and Their Roles

In many cases, treatment can mean caring for multiple problems, so we address all aspects of a child’s illness in one place. Our unique multidisciplinary approach has brought together the best individuals and practices throughout the hospital to provide complete care and heal the patient as a whole.

The Hemophilia team has pediatric nurses, and also family nurse practitioners, to manage our adult patients. Our child life specialists, social workers, therapists, and other clinical professionals help families understand their children’s diagnosis, treatments, and the care needed at home and throughout their life. Our specialists understand the concerns and fears kids may have at every stage of the healing process and assist in preparing them for the fastest possible recovery. Our team works closely with the Arizona Hemophilia Association to coordinate each patient’s involvement in its programs, support groups, and camps.

Together, we bring world-class medical and research expertise, as well as hope for a cure for bleeding and coagulation disorders, to the Southwestern United States and beyond.
