Stacked on the bookshelves in his office in Burlington, Massachusetts, Bill Brodnitzki has folders containing information on everything from pricing to supply chain management – valuable material that he acquired while taking his MBA at Babson College.

Silverlink’s expanding team of employees includes a growing band of Babson MBA graduates.
