Population is compounding
Sherman added 20% from 2020–2025 (Census). Grayson County crossed 153,600. This is no longer a static county-seat town — it is a DFW-north industrial node.
Sherman & Grayson
The census finally agrees with the Chamber.
Sherman is no longer a slow county seat waiting on DFW. It is a semiconductor and hospital growth market with a rural service area attached.

Sherman and Grayson County, 2020–2026e
Outpatient follows rooftops and jobs
Texas ambulatory health jobs grew 2.7% CAGR over a decade vs. 1.9% overall (Texas Real Estate Research Center). Sherman already shows a high concentration of medical establishments because it serves a rural hinterland plus southern Oklahoma.
The hospital map is being redrawn
AHS Sherman Medical Center (former Wilson N. Jones) remains the in-town campus. TMC in Denison is the regional flagship. A $400M third hospital opens 2028 on the west side. Outpatient will fill the gaps between those three poles.
Purpose-built medical is scarce
The largest in-town office product is 1982 Class B at $19–21/SF. The one clean purpose-built MOB sale on the board is 4,397 SF at $273/SF. New product has a real gap to fill — if the delivery model matches what Sherman rents can support.
The employment shock
Medical office demand in a market this size is not just aging. It is occupational health, family formation, and the specialists who follow a new middle class of fab technicians.

Read-through for 909
A 35-year-old median age plus a fab hiring wave plus a 2028 hospital is not a sleepy medical market. It is a market that will over-absorb whatever purpose-built product actually gets built — if the product is sized to the rent.
