Seeking an experienced senior care provider for two elderly sisters, both with Alzheimer's. Our care concerns are: Light Housekeeping, Mobility Assistance, Bathing / Dressing, Feeding, Meal Preparation, Companionship. Assistance with toileting is one of our requirements. Personal care required, including feeding. Additional responsibilities include meal preparation and light housekeeping (sanitizing bathrooms, keeping the floors clean, cleaning up messes if they occur, cleaning up after meals). Japanese-speaking / understanding Japanese culture preferred, but not required. My parents can no longer communicate in English, and have limited understanding of direct verbal communication. We would like to have someone come regularly for a trial basis, with potential to increase hours if there is a mutual desire to do so.
