Companion Care Needed - Full-time / Part-time

About who needs care: He has Aphasia, which is a language processing disorder, but does not effect cognitive ability. He has short term memory loss that causes distress and needs to be re-oriented to the environment around him. About the care needs: Interest in artistic ventures would be lovely. His family are mostly designers and artists. He is a more open personality and imaginative. My father is quite happy but gets moody easily (low locus of control), so someone who is grounded but able to excite him into doing a task is the best. Someone who takes charge. He mimics whatever the personality of who is around him, somewhat similar to a child. Services needed include: companionship.
