The Legacy of the Shamrock Shake

The Shamrock Shake was created in 1967 by Hal Rosen, a Connecticut McDonald’s Owner and Operator who made the delicious, mint shake in celebration of St. Patrick’s Day. It later debuted in select locations across the U.S. in 1970, and was an instant success.

In 1974, sales from the shake helped to build the very first Ronald McDonald House in Philadelphia. The mission began when the daughter of a Philadelphia Eagles player was being treated for Leukemia. Together with with a local McDonald’s Owner and Operator Hal Rosen, McDonald’s founder Ray Kroc, the Children’s Hospital of Philadelphia and the Philadelphia Eagles, the family raised enough funds through Shamrock Shake sales to help open the first Ronald McDonald House as a way to keep families close during difficult times.
