"Blood disorders, including hemoglobinopathies, bleeding disorders, clotting disorders, and bone marrow failure syndromes, affect millions of children all over the world. I have been fascinated by blood since the early days of my medical education with a particular interest in the complex systems of bleeding and clotting. I love the detective work that goes into the diagnosis of these disorders and I’m excited about all the novel therapeutic options that are available to our patients, including new medicines and gene therapy. I enjoy being able to work with children and families to offer treatments that can get them back to enjoying a healthy life!"

  • Gavin D. Roach, MD, MS, is an attending physician at Seattle Children’s Hospital, Associate Professor of Pediatrics at the University of Washington School of Medicine, and the Medical Director of the Thrombosis Program at Seattle Children’s.  Dr. Roach grew up on the East Coast before moving to Los Angeles for his Pediatrics residency at UCLA.  He stayed in LA to complete his hematology/oncology training and then joined the UCLA faculty in 2014.  While at UCLA, Dr. Roach was the Director of Pediatric Hematology and oversaw the treatment of all patients with benign hematologic disorders in inpatient and outpatient settings.  In addition, he treated patients with bleeding disorders at the Hemophilia Treatment Center at the Orthopaedic Institute for Children in Downtown Los Angeles. He served as the Program Director of the Fellowship Training Program in pediatric hematology/oncology and was involved with medical education at all levels of medical training, including at the David Geffen School of Medicine, in the pediatrics residency training program, and with the pediatric subspecialty fellowship training programs at UCLA.

    In 2021, Dr. Roach left sunny Southern California to take on a new position as the Director of Thrombosis at Seattle Children’s.  He is looking forward to the opportunity to explore Seattle and the surrounding areas, as well as develop a world-class pediatric thrombosis program serving the children and families of the Pacific Northwest.

      Dr. Roach is excellent. He treated our daughter from 12 day to 12 months old, following a traumatic brain injury resulting from a rare clotting disorder. His demeanor is caring and professional, and his methods are research based. He knows tradition solutions as well as the latest pediatric hematology research, including active studies, and treats both children and parents with utmost respect. He was able to explain in detail our daughter's diagnosis and path forward--including potential alternatives (and limitations of current research). HIs depth of knowledge, honesty and bed-side manner are unlike any of the several dozen doctors we work with. As a mother, I felt compelled to write this review because I wish their was a better way to learn these things about doctors ahead of time. You are in excellent hands with Dr. Roach.
