The Alzheimer's association and AARP have resources on this. topic. Once you know what to look for, I'd recommend you start interviewing potential caregivers and caregiver companies. In addition to wanting to hire from a company that does background checks and bonds its employees and takes care of government compliance issues (such as worker's compensation, unemployment, tax collection, etc.), you want to make sure the person's personality is a good fit for the person that will be cared for.
