I'm am trying to find a service to drive my Mom to and from doctor. Any suggestions?

Looks like Area 7 is your office of aging. What do you mean "they call back and say call" Is this another recording? If so, maybe they need to be notified their system is broke or someone not doing their job. For me O of A is 10 miles away. I can easily drive to the offices. Look in your phone book, see if all your County agencies fall under one number with extentions. If so, call the main number and tell them you cannot get thru to the O of A and can someone get a message to them and a person call you back.

If there is a local bus company, they likely have a special medical transport service...many do

Here is the website.
I see several numbers listed. I would call one after another until I got a reply. Perhaps you could leave a more detailed message?

Is your mom on Medicaid? Indiana medicaid does provide transportation to doctors appointments. You have to call Southeastrans at least 2 business days in advance.
