After 30 years in the drug store sector, Michael Bloom left CVS Caremark in September 2011 to become president and COO of Family Dollar Stores. The extreme-value chain has adopted an aggressive growth strategy in recent years, and plans to open 450 to 500 stores in 2012.

Family Dollar is equally committed to improving existing locations. Under its ambitious store-reinvention program, an estimated 1,000 locations are scheduled to be renovated, relocated or expanded this year.
