Health Dialog is a wholly owned subsidiary of Rite Aid Corporation that provides care management, employee wellness, and decision support provider. The company is based in the United States and headquartered in Boston, Massachusetts. The company was founded in 1997 to address overutilization. Research done by John Wennberg and The Dartmouth Institute for Health Policy and Clinical Practice found unwarranted variation, which means that the amount of healthcare services consumed per capita varies significantly between different regions of the United States, and that areas that deliver more care or higher-cost care do not necessarily show improvements in health quality outcomes. The company seeks to reduce unwarranted variation in the U.S. healthcare system through care management and shared decision making.
In Boston Business Journal's 2016 feature on the growth of private Massachusetts companies, it has named Health Dialog as "one of the area's 50 fastest-growing companies as well as one of the area's 100 largest private companies", with a two-year sales growth of 179% and a revenue of $136 million in 2005 making it the 5th largest 2005 revenue.
