Live in caregivers who maintain another residence typically work in teams. There will be two caregivers. They are with the care recipient during daytime hours, as well as, spending nights in the care recipient's home. They provide "around the clock" care. This type of live in care is more appropriate for individuals who have higher care needs. Companionship care is utilized in this manner to prevent loneliness as well. Caregivers will likely be providing assistance once, twice or more times throughout the night and will therefore experience significant disruptions to their sleep. The fact that they live with the care recipient is thought of as a convenience to the care recipient not as a benefit to the caregiver. 
 They are not providing care in exchange for room and board.

"I was so worried about having strangers in my house, but now I feel very comfortable. Your people are prompt, friendly, and very helpful. One or two of them are even starting to feel like family.

“When Dad died, I was so worried I wouldn’t be able to take care of Mom by myself. Your company has meant my mother can live in her own home and still get the help she needs to stay healthy. Your people have been a God send.”
