Are there social networks where seniors can choose a caregiver and have them come home and take care of them?

Your Family, Friends, and Neighbors
They are the best source of assistance, so consult them about the care you need.
Community and Local Government Resources
Ask your community about the services they offer. Social workers and health care providers can suggest ways to get access to the best care you seek. If you belong to a religious group or community, it’s a good idea to talk to the head of the group about any assistance or service they have for seniors.
Consult Geriatric Specialists
These specialists are trained to work with seniors and can help you with the resources to meet your needs. When your family members are not accessible, these specialists can be of great help.
