Peer support has begun to gain traction as a mechanism for improving well‐being in medicine. In this paper, we share our experience building, training, and piloting a peer support team based on a “critical incident stress management” model. The HOPES team (Helping Our Peers Endure Stress) is dedicated to, and composed entirely of, members of our division of pediatric hematology/oncology. Peer support will not solve all the well‐being problems afflicting medicine. It is, however, a very good place to start.
