Major employers, ranked: the school corporation first, the hospital system second — and a data center that is not yet an employer

As of November 2026 · workforce figures dated in their sentences

How this ranking is built, stated before it is used: An unincorporated CDP has no employer census of its own, so this set ranks the institutions that employ people on or for this ground, by workforce, with each entry's size given at its system's strength and its local weight stated separately. Where the two diverge — a giant system with a small local footprint, a modest firm headquartered here entire — the divergence is the entry's point.

1. Penn-Harris-Madison School Corporation — the ground's largest employer of people who work on it. The federal Common Core of Data for 2024–25 counts PHM at 1,278.01 full-time-equivalent staff, of whom 615.01 FTE are teachers, serving 11,329 students in fifteen schools from a headquarters at 55900 Bittersweet Road, Mishawaka. The corporation is seated outside the CDP, but five of its schools stand inside it, on this build's Schools section count — which makes the district simultaneously the ground's biggest off-site institution and its biggest on-site employer. (A salary-database aggregator counts 3,173 PHM pay records for 2025; that is a count of people paid at any point, not an FTE figure, and the two are printed here once, distinguished, because retellings swap them.)

2. Beacon Health System — the largest system touching the ground, with a clinic-sized local footprint plus a hospital at the line. Beacon counts its associates two ways in its own copy: "more than 7,000" in its December 2020 by-the-numbers, "more than 8,000" in later system copy; both stand dated and unmerged. The system is headquartered in South Bend. On the ground its weight is the Granger clinic layer carried in the Health leg, and at the boundary the Beacon Granger Hospital, opened 2019 — which the geocoder seats in Mishawaka, as the Health leg's verdict prints. System size second on this list; on-ground weight smaller than the school corporation's, and printed so.

3. Martin's Super Markets — the ground's grocery anchor, a chain of thousands with two local seats. At its acquisition by SpartanNash (announced November 2018, closed 31 December 2018), Martin's operated twenty-one stores with approximately 3,500 employees and more than $450 million in sales, headquartered in South Bend; a current employment-verification profile puts the chain at over 3,000 people across twenty-two stores. Its Granger weight is its two seats on the corridor, carried in the Businesses leg — including the Heritage Square store whose 2006 opening is settled and the Store #16 question, which rides the Businesses leg's named gap (GAP-BIZ-2) to the Tribune archive and the company's own history.

4. Microsoft, EKI campus — not yet an employer; ranked here to be excluded honestly. The campus is the ground's largest construction project and, as of November 2026, employs no operating workforce on it: the roughly 300 permanent jobs attached to the project are county officials' figure for a finished campus, the $77.5 million land purchase closed in 2024, the $65 million memorandum was voted 6 October 2026, and the site's dewatering was approved 2 November 2026 for a mid-December 2026 to early April 2027 window. When the campus hires, this ranking changes; as of this section's date, it has not.

5. Big C Lumber — the ground's own headquarters firm. The Businesses leg carries Big C as the county firm that put its headquarters on this ground — the list's one employer that is Granger's by seat rather than by footprint. Its workforce is not published at a citable figure in the sources reached; named gap, settler the company's own published figures and the county economic-development rosters. It is ranked last by provable size and first by belonging, and the entry prints both facts rather than resolving them.

The county weather around the set: For scale only — not as a Granger figure, since no place-of-work series exists for a CDP — the Bureau of Economic Analysis counts St. Joseph County employment by place of work at 161,256 for 2024, with health care and social assistance the largest sector at 23,117 jobs (14.3%). The ranked set above is what that county weather looks like from one suburb: schools first, health second, groceries third, and the future fourth, still in the ground.
