Dayton Senior AdvisorWhich Ohio counties does Dayton Senior Advisor cover?

Why is Warren County not included?
Warren County, south of Dayton, belongs to the metro area to its south and to a different Area Agency on Aging and ombudsman region, so Springboro, Franklin and Lebanon facilities are not in this directory.
Families on the Montgomery-Warren line often compare Miamisburg, Centerville and the south Dayton suburbs with Springboro; the Ohio Department of Health's lookup covers every county if you need to check a Warren County license yourself.
Which Miami Valley county has the oldest population?
Preble County: 23.2% of residents were 65 or older in 2025 Census estimates, with a median age of 43.7, against 23.1% in Darke, 21.8% in Clark, 21.3% in Miami, 20.2% in Montgomery and 19.9% in Greene County.
Preble also has no general hospital in CMS's list, so many Preble families weigh the Eaton nursing homes against options in Dayton's western suburbs.
Do all six counties share one aging agency and one ombudsman?
Yes. The Area Agency on Aging, PSA 2 serves all six (plus Champaign, Logan and Shelby), and the Region 2 Long-Term Care Ombudsman covers the same nine counties, so one phone number reaches help wherever a parent lives.
What differs by county is Adult Protective Services, which each county's Job and Family Services department runs, and where the Medicaid application is processed.
How many older adults live in the six counties?
Census Bureau estimates put 218,452 residents aged 65 and older in the six counties on July 1, 2025, including 24,659 aged 85 and older, the group most likely to need daily help.
Montgomery County holds about half of them in raw numbers, but Preble, Darke and Clark have higher shares of older residents, which is why so many families there look at Springfield, Greenville and Eaton options as well as Dayton's.
