GrandCare was licensed by the California Department of Public Health and accredited by the Joint Commission to provide home health services in Los Angeles and surrounding counties in 2003.

In 2011, the company expanded its licensed and accredited services in Los Angeles County with the addition of hospice and palliative care.

In 2014, GrandCare acquired American Health Services of San Diego, a licensed home health agency, and subsequently rebranded the agency to GrandCare San Diego.
