"I’m motivated by the connections I make with each patient and committed to improving their daily experience living with and beyond a cancer diagnosis. I believe excellence in oncology care is built on team science, and I’m privileged to work with an incredible multidisciplinary team in Seattle, where translating discoveries from the lab bench to the patient is a familiar reality."

  • Erin Crotty, M.D. is an attending physician and pediatric oncologist in the Brain Tumor Program at Seattle Children's Hospital and Assistant Professor at the University of Washington School of Medicine. She cares for children and adolescents with brain and spinal cord tumors, and is the medical lead for the Retinoblastoma Program alongside oncologic ophthalmologist, Andrew Stacey, M.D. She is involved locally and internationally in early phase clinical trials for children with brain tumors and serves as site Principal Investigator for the Pacific Pediatric Neuro-oncology Consortium (PNOC). Her research and clinical interests focus on implementing new immunotherapies, like CAR T cells, and precision medicine approaches for difficult-to-treat brain tumors.

    Dr. Crotty completed her pediatric residency training at Children's National Medical Center in Washington, D.C. and returned home to the west coast for her hematology/oncology fellowship at Seattle Children's Hospital/University of Washington, where she completed additional translational research training in the laboratory of James Olson, M.D.,Ph.D. at the Fred Hutchinson Cancer Research Center, studying novel protein therapeutics.

      Dr. Crotty is an incredible doctor who treats not only our son, but our entire family, with the utmost care and respect. She became our primary oncologist shortly after joining Seattle Children's brain tumor team and I could not believe we got so lucky to be connected with her when our son was diagnosed with brain cancer. She has helped us navigate the most difficult conversations and decisions with expert information, thorough explanation, and so much compassion. I couldn't recommend Dr. Crotty more for her expertise and caring nature.

Research Description

Dr. Crotty's research interests include immuno-oncology and precision medicine approaches for children with brain and spinal cord tumors. Dr. Crotty is particularly interested in the translation of promising therapies from the lab bench into innovative clinical trials for patients. She collaborates with international cancer consortium members in the design and implementation of clinical research.

Dr. Crotty's prior work in the Olson Laboratory at the Fred Hutchinson Cancer Center (now located at Seattle Children's Research Institute) studying novel immunotherapy for medulloblastoma provided the preclinical foundation for an upcoming international CONNECT Phase I clinical trial, which she will lead as co-Principal Investigator. In 2022, she was awarded the Children's Cancer Research Fund Emerging Scientist Award to study a novel cell-free DNA sequencing technique to reliably detect residual disease left over after treatment in the cerebrospinal fluid (CSF). For children with brain tumors, this platform could enable personalized treatment with reduced toxicity.

Research Focus Area

Early phase clinical trials for pediatric brain tumors, Cancer biology, Immunotherapy, CAR-T cells, Epigenetic modifying agents, cell-free DNA
