McKesson's Health Mart, a leading franchise with more than 3,000 independently owned pharmacies, achieved the highest ranking in overall customer satisfaction among chain pharmacies in the J.D. Power and Associates 2012 U. S. National Pharmacy Study. This is the third time in four years that Health Mart has ranked the highest among chains.

The study was fielded during the summer, with responses from more than 12,700 customers who filled a new prescription or refilled a prescription during the three months prior to the survey period. The study measured overall customer satisfaction using five key factors: prescription ordering, store, cost competitiveness, pharmacy staff, and pharmacist.
