Walgreens, founded by Charles Rudolph Walgreen in 1901 in Chicago, is a major U.S. pharmacy and retail chain operating under the publicly traded parent, Walgreens Boots Alliance (NASDAQ: WBA). Headquartered in Deerfield, Illinois, it provides prescription services, health and wellness products, photo services, and expanded healthcare offerings including immunizations and diagnostic screenings. As of late 2025, the company operated thousands of retail locations across the United States and Puerto Rico, serving roughly 78% of Americans within five miles of a store. Walgreens maintains omnichannel operations—blending in-store, online, drive-thru, and home delivery services—and has strategic healthcare partnerships, notably with VillageMD. Under the direction of new CEO Mike Motz, following the August 2025 purchase by Sycamore Partners, Walgreens continues to emphasize core pharmacy execution, digital innovation, and integrated care solutions.
