I want to get others in to help me care for parents. Mom has Medicare and AARP. Dad has AARP. Who should I call?

Medicare may not do much unless a person was just released from a hospital. Much depends on the AARP Insurance they have. I'd check with them both, to be sure. Also, go to your state's Web site under something similar to "aging services" to look for community based help.
Good luck,
Carol
