My siblings and I are faced with finding extra care for our dad, like ASAP. Where do we start?

If your dad is a veteran, call the Veteran’s Administration to see what kind of help they can provide.

Care.com , Next Door . com , Nesterly.com , elder services . Get a social worker to help you find services .

We really need more info, needing extra care means a lot of things.

A little more info will help. How old is dad?
What is your dad's condition? Dementia? Stroke? Mobility?
Is dad a Veteran?
The VA might be able to offer a LOT of help or a little help.
You can start with your local Senior Service Center. They typically have Social Workers that might be able to help you. And they may have programs that would provide help.

care.com. A good place to start.
If your elder is currently hospitalized or in rehab lean heavy on the social workers for guidance.

You might tell us more so that we may be able to help you more.
