In other changes, Gary Philbin was promoted to enterprise president of Dollar Tree. In his new role, Philbin will oversee store operations, merchandising, marketing and real estate across all banners including Dollar Tree, Family Dollar and Dollar Tree Canada.



With more than 15 years at Dollar Tree, Philbin was most recently president and COO of Family Dollar, where he oversaw the development of strategic initiatives and the successful achievement of budgetary, synergy and transition goals following Dollar Tree’s acquisition of Family Dollar in July 2015.

“I am pleased to have the opportunity to lead the Dollar Tree, Family Dollar and Dollar Tree Canada teams in this new role as Enterprise president,” said Philbin. “Additionally, I would like to welcome Duncan Mac Naughton to the Family Dollar team. Duncan is an accomplished retail leader and will be instrumental in continuing to develop and improve the Family Dollar banner through an intense focus on the customer. I also want to thank the thousands of Family Dollar team members across the country for their dedication and efforts through the past 18 months of integration.”
