Anjali Pawar with young patientOur multidisciplinary team of experts at UC Davis Hemostasis and Thrombosis Center (HTC) have diagnosed and treated the unique clinical characteristics of hemophilia, von Willebrand disease and other inherited bleeding and clotting disorders for more than 50 years. The center's hemostasis laboratory conducts specialized diagnostic testing that is seldom available at outside laboratories or in other clinical settings. Comprehensive services are provided by a specially trained core team experienced in treating bleeding and clotting disorders, including pediatric and adult hematologists, nurse coordinators, social workers and a physical therapist. We collaborate with HIV specialists, hepatologists, orthopedic surgeons, gastroenterologists, a dental hygienist and obstetricians/gynecologists. When necessary, referrals can also be made to outside specialists, with medical coordination by our team.
