Dr. Marilyn J. Manco-Johnson
MD

Dr. Marilyn Manco-Johnson received a BS from Penn State University, State College, PA and an MD from Thomas Jefferson University, Philadelphia, PA.  She trained in pediatrics and pediatric Hematology/Oncology  at the University of Colorado and Colorado Children’s Hospital.

Dr. Manco-Johnson’s career has been in clinical care as well as clinical and translational research of bleeding and clotting disorders.   She oversees a large clinical and research program that cares for 2000 children and adults with coagulation disorders. The Colorado HTC integrates research into the comprehensive evaluation and management of bleeding and clotting disorders.  Some examples of this research include development of novel global assays to evaluate coagulation; conduct of investigator-initiated and well as Pharma-sponsored trials for new therapies of hemophilia and thrombosis; pharmacokinetic and pathophysiological studies in rare clotting disorders; and animal models of human coagulation disorders.
