During the PGY III year, the resident increases his or her involvement at the outpatient site to half time throughout the year. During the outpatient experience, the resident is involved in the full range of treatments; including short- and long-term dynamic psychotherapy, cognitive and behavioral therapies, family and couples therapy, group therapy, and psychopharmacological therapies.

For six months, half time, residents are assigned to the consultation-liaison and geriatric psychiatry rotations at either BIDMC or BWH where they learn the specialized skills of these branches of psychiatry, including differential diagnosis at the medical/psychiatric interface and appropriate psychiatric treatments in the medical milieu.During this time, residents spend two weeks in a geriatric psychiatry experience, which includes outpatient, acute rehabilitation, and nursing home settings. 

For the remaining six months, half time, residents are assigned to the Community Psychiatry rotation at the Massachusetts Mental Health Center. Residents function as members of multidisciplinary teams in a variety of settings including the PREP (Prevention and Recovery in Early Psychosis), Continuing Care, DBT (Dialectical Behavioral Therapy), MI/PSB (Mentally Ill with Problematic Sexual Behavior) and Healthcare for the Homeless teams. This rotation provides a unique opportunity to learn about the general and specialized care of patients with severe and chronic mental illness in the community.
