Thrombosis and Hemostasis

Thrombosis and Hemostasis

Our team is dedicated to treating children with bleeding and clotting problems. The team includes physicians, nurses and social workers with special interest in hemophilia and coagulation factor deficiencies. Beyond the direct care of children afflicted with bleeding and clotting disorders, our goal is to help parents and families with their inevitable emotional challenges. We accomplish this through family education, social interactions among families of affected children, home care and additional support.

We engage in ongoing research for developing innovative therapies and for addressing safety issues, such as complications or risks that may be associated with medications. We educate and mentor future trainees in diagnosis and treatment of children and adolescents with bleeding and clotting disorders. We also participate in clinical trials related to adolescent bleeding and clotting problems.
