In-home care and services. Any advice?

In-home visits from podiatrist SHOULD be covered by Medicare. Be sure to ask.

If your Mom has a regular podiatrist he/she may do it. If not maybe they can recommend one. Call local NHs and see what Podiatrist comes in for their residents. Hairdressers, does Mom have one. Have you asked if she/he is willing to come to your home? If not, does she/he know of a hair dresser who will. Again a NH/AL may know of one. I live in a small town and the hairdressers I know will go to where their clients are, whether their home or a facility.

Call the podiatrists in your area and ask if any make house calls.
I suggest you also call salons and ask. If there is a "Beauty Academy" or "Beauty School" in your area call and ask if they will do a home visit for a "shut in". A student probably would not do this unless they have an instructor with them if it is not something they offer you might want to suggest it as it is a good idea.
You could also go to a couple of "Residential Facilities" (Assisted Living or Independent Living) as many have Salons on site that have independent contractors that may do home visits.
