Head Counsellor

Because of their training in psychology, technically the ships'/facility's Head Counsellor is considered part of Starfleet Medical. The Head Counsellor is responsible both for advising the CO in dealing with other people and races, and in helping crewmembers with personal, psychological, and emotional problems.

The Head Counsellor is technically under the authority of the Chief Medical Officer. However, the ships/facility's Head Counsellor is considered a separate entity and considered a member of the Senior Staff.
