Our expert team provides comprehensive clinical care and treatment for children, adolescents and young adults with cancer and blood disorders.


Peter Shaw, MD Hematology / Oncology

Dr. Shaw joined the Johns Hopkins All Children’s Cancer & Blood Disorders Institute in August 2016 as deputy director. He works collaboratively with the entire hematology-oncology team and other pediatric specialists at Johns Hopkins All Children’s Hospital to provide comprehensive care throughout each patient’s cancer journey and provide the best outcomes for children, teens and young adults with cancer. Dr. Shaw is recognized nationally as a leader in the areas of adolescent and young oncology (AYA). He is founding member of the Consortium of Adolescent and Young Adult Cancer Centers and helped develop internally recognized standards for care of this population. He is expanding the AYA program at Johns Hopkins All Children’s to enhance continuity of care into adulthood through multidisciplinary collaboration with physicians at Moffitt Cancer Center. He will also support the institute’s fertility preservation program, which helps pediatric cancer and bone marrow transplant survivors enjoy optimal health and the opportunity to become parents in their adult years.
