Most agencies describe their service area as a list of towns and zip codes. That list shows where the agency says it works. It does not show that an aide can reach your street on the days and hours you need. Check the list against your address before you compare anything else.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
Ask where the aides for your address are based
Ask which office the aides assigned to your address report from, and whether those aides live within the service area. An agency that staffs from a distant office may list your town on paper while open shifts go to aides who drive across the county. Ask how long the typical trip runs from that office to your door, and whether the answer changes at the start and end of the day.
Use the county picture to frame the question
Read the supply guide for your county before you call, so you know how the local pool of agencies is spread across the region. The agency pages linked below group providers by the towns they serve, which gives you a starting map. Use them to check whether an agency's stated list matches the towns it appears to cover.
Start with how to read a caregiver-supply map for your county. For west St. Louis County towns, see the Chesterfield, Ballwin and Wildwood agency list. For north county towns, see the Florissant and Ferguson agency list.
Questions for the first call
Ask which towns the agency staffs directly, which it covers from another office, and which it does not cover at all. Ask how many aides live within your town's service area. Ask what happens when the usual aide for your address is out, and whether the answer is the same on a weekday morning and on a weekend evening.
Confirm the towns in writing
Ask the agency to name the covered towns in the agreement or the start paperwork. A yes on the phone does not carry into a later schedule change. If the written towns differ from what you heard on the call, ask which version governs before you sign.
