Live in Gwinnett County Georgia. My Mom's doctors are 7 miles away, but sometimes I have to work and can't get her there. I am looking for Elderly Transportation that isn't going to cost an arm and a leg.

They have "limited" transportation services available, and they run a voucher scheme. If you don't ask you don't get! - good luck, hope this helps.
