Dr. Joan Fisher, the George Mark Children’s House Medical Director, is a graduate of the Stanford University School of Medicine with post-graduate training in pediatric hematology, oncology and bone marrow transplant. She received additional training in pediatric palliative care from the Center for Palliative Care at Harvard Medical School.
Joan is the director of outreach for the Division of Pediatric Hematology/Oncology for Stanford University. Her work takes her to California Pacific Medical Center in San Francisco and John Muir Medical Center in Walnut Creek. Wherever she goes, she takes the opportunity to integrate the principles of palliative care into the practice of pediatric medicine. She also spreads the good word about what happens here at George Mark. While most feel that this is only important at end of life, families understand the importance of good palliative care from the beginning of any journey that threatens the welfare of their child. For Joan, taking care of children with medical needs—and their families—while making every day their best day, is what makes the practice of pediatrics worthwhile.
Joan has lived in many places, yet the Bay Area is her home. She is honored to be able to serve this community in a capacity that she loves, and looks forward to many years of memories with the George Mark family. Joan and her husband, Allen Eskenazi, a pediatric physician, reside in San Carlos.
