GREENWICH HOSPITAL’S Outpatient Center is an important healthcare resource for Greenwich residents who have no medical insurance or are under-insured. Each year, more than 5,000 adults and children visit the Outpatient Center and Pediatric Outpatient Center for medical and dental diagnosis, treatment and preventive care.  You may qualify for membership in the Outpatient Center if you are a Greenwich resident who is under or uninsured, or your income falls within government poverty guidelines. Services are by appointment.
