I am looking for a live-in caregiver for my 63 year old mother, who has bi-polar. Most of the time, she is quite lucid, and simply requires help in the home. However, if she is in a manic state, she does require more care, and someone who is able to deal with a strong personality affected with a mental illness. This role will also be providing full housekeeping, laundry, meal prep, grocery shopping and errands for my home as well. We are looking to make an 18-month commitment for the right candidate.
