RadioShack last week confirmed it had recruited Michael De Fazio, one of the architects behind Duane Reade's new store formats, to help the small-box specialty retailer build its retail presence. De Fazio joins a team that includes Troy Risch, who came to RadioShack from Target as EVP operations in December, and Huey Long, formerly of Wal-Mart and now RadioShack EVP strategy and consumer insights who also signed with RadioShack in December.
