Are there any transportation companies that will take my elderly Mom in a wheelchair to her doctors appointment?

De Soto cab has wheelchair service. Rates look very reasonable, and you only have to go 3-4 miles.

Contact the bus service for your county and see what they can suggest. You can also contact your health insurance company and see if transportation is covered. Also, contact the county agency for aging and the association for whatever medical problems are involved for help. There's a way to get this done. My 92 year old aunt in Downey has door to door service for her and her wheelchair and aide for 25 cents a trip.
