Just about a month ago, Mammoth Holdings announced that it had hired former Dunkin’ President and CEO David Hoffmann as the new Chairman and CEO of Mammoth Holding, LLC, the Atlanta-based conveyor car wash operator. Mammoth has a portfolio of brands across 10 states for which Hoffmann, who joined the Mammoth Board in August, will now be responsible. In other Dunkin’ news, Dymatize, the purveyor of athletic nutrition products, announced a expansion of its ISO100 protein powder line to include a collaboration with Dunkin’. The company will launch two new products in the flavors of Dunkin Cappuccino and Mocha Latte. Dymatize ISO100 in Dunkin’ Cappuccino and Moche Latte flavors will have 25 grams of protein per serving along with 120 calories and less than one gram of sugar. It is the first restaurant collaboration for the Dymatize brand as well as the first for Dunkin’ in the athletic nutrition space.
