The San Bernardino County Business Landscape
San Bernardino County is the largest county in the contiguous United States by area and a cornerstone of the Inland Empire economy. Logistics and warehousing dominate the valley floor near the I-10 and I-15, while county government, healthcare systems, and California State University, San Bernardino anchor the county seat. To the north, the High Desert cities of Victorville, Apple Valley, and Hesperia add manufacturing, retail, and the Southern California Logistics Airport — all within SonicVoIP's home service area.
