Simon Lejeune graduated from the Cambridge Hospital Adult Psychiatry Residency Program in June 1989. He then had jobs in different parts of the department – at Metropolitan State Hospital, on the Tuesday OPD team, and on the inpatient units. He was part of the team that started the SAU, the first DMH replacement unit and first locked unit at CHA, and then director of inpatient psychiatry. After 17 years at Cambridge Hospital, he moved to Massachusetts Institute of Technology when he continued to practice the principles of community psychiatry that he learned at Cambridge Hospital. After 14 years at MIT and 2 year stint as medical director of a intensive PTSD program at MGH, he returned to the outpatient department at CHA. He was the team doctor at the Victims of Violence program until it closed and is now on the RISE (first episode psychosis) team and the Haitian team.

His special interests are the treatment of major mental illness and ptsd, young adult development, substance abuse, and suicide prevention. He has been supervising residents at CHA since he graduated.

Outside of work he likes to be with his family, painting, baking, and being outside. Trying to be a birdwatcher was part of his pandemic survival plan.
