Whether you run a healthcare practice in O'Fallon or a medical staffing business in Belleville anywhere across St. Clair County, you're in a market anchored by two major health systems serving a combined regional population of over 670,000. HSHS Saint Elizabeth's Hospital opened a new 114-acre state-of-the-art medical campus along Interstate 64 in St. Clair County, and Memorial Hospital East serves the growing eastern corridor, together employing thousands of healthcare workers and driving consistent demand for every physician practice, home health agency, and medical supplier in the county.
Whether you run a retail business in Fairview Heights or a restaurant in Shiloh anywhere across St. Clair County, you're benefiting from direct access to a bi-state metro market of 2.8 million people just across the Mississippi River. Fairview Heights is one of the top retail destinations in southwestern Illinois, drawing cross-river shoppers from Missouri who save on Illinois sales tax rates, and the O'Fallon–Shiloh corridor has become one of the fastest-growing commercial strips in the St. Louis metro, with new dining, fitness, and service businesses opening steadily as residential development continues to push eastward from Scott Air Force Base.
