Local context

Local healthcare landscape in O'Fallon

HSHS St. Elizabeth's Hospital gives its address as 1 St Elizabeth's Blvd, O'Fallon, Illinois 62269, and its home page lists cancer care, convenient care and heart care. The city's history page says St. Elizabeth's Hospital opened a campus in O'Fallon in 2018, while the 2040 Master Plan places Memorial East (BJC) Hospital in Shiloh. The city's Green Mount Medical Campus TIF page says a plan approved in 2011 came with the rezoning of land for a Hospital Sisters Health Systems development for a future medical facility and medical office buildings. The same history says the area was called Ridge Prairie, notes Rock Spring in the area east of Highway 50 and Scott Troy Road and says a subdivision, North O'Fallon, was added in September 1854, and says the Vine Street Market opened in the newly built O'Fallon Station in 2019, contributing to a re-energized historic Downtown District.

Our plan

What we'd prioritize for a O'Fallon practice

Picked from the figures above by fixed rules.

  1. An opening for plastic surgeons

    None of the NPI-registered plastic surgeons list a practice address in O'Fallon; nationally there is one for every 58,824 residents. That leaves fewer local competitors for a plastic surgeon in search; see our marketing for plastic surgeons.

  2. Stand out among the chiropractors already here

    O'Fallon has 4.4 times the US number of NPI-registered chiropractors per resident, one for every 759 residents. A chiropractor here needs a clear focus and real reviews: see our marketing for chiropractors.

  3. Start with reviews and the Google Business Profile

    One NPI-registered dentist per 990 residents in O'Fallon (US: one per 1,340). The Google Business Profile comes first, then review management.

  4. Put elective and cash-pay services first

    The median household income in O'Fallon is $105,982, against $80,734 for the US. Elective work earns its own pages and budget, with Google and Facebook ads.
