About Senior Home Care Services

Premium Live-in Care Staffing Since 2010

Grandma Joan is a nationwide, award-winning staffing service that has been helping discerning families recruit, screen, and hire premium live-in caregivers since 2010.

We act as the family’s private headhunter/recruiters, finding and screening the top live-ins in the country for the care recipient’s specific needs.

We can help the family get set up with a turnkey payroll solution to pay the caregiver, following all state and federal employment laws and workers comp requirements. Household live-ins are all that we do.

In most states, the cost is about the same as a nursing home and half the cost of 24-hr homecare through an agency.

For over a decade, Grandma Joan’s consumer-based home-care model has been providing American families with a more affordable solution to choose from than the business directed models of nursing homes and home-care agencies.

Grandma Joan's Story

We started out as a state-licensed home care agency in 2010. Our Grandma Joan’s home-care model was born from an exit survey with one of our original home care agency clients. He was distressed about the need to continue our professional live-in services for his mom. She was living alone and had Alzheimer’s; however, he was no longer able to afford our agency’s rates. It was from this client’s need that Grandma Joan LLC was born. We helped him find, screen, and contract with a qualified independent live-in, all for a one-time set-up fee. He paid the independent provider directly and on the books, cutting out our agency overhead. Grandma Joan’s service model was an overnight success, and within a year of its launch, we went nationwide.
