Customer Reviews

Aurelie Corbel Executive Director - Delivery, HEC Executive Education

“Allyson Stewart-Allen has brought valuable strategic insight, fresh ideas, and an endless supply of energy to our project. We’re lucky to have her as an extended part of our team.”

Kristin Wolfe VP - Global Industry Affairs, SAB Miller

“Allyson creates a no-fuss, constructive environment in which executives can discover for themselves what will move the dial on their collective performance… I saw her achieve exactly that with my own Board in a recent one-day workshop and the results exceeded all my expectations.”

Rebecca Oldfield Global HR Director, Infineum

“The Working with Americans help from International Marketing Partners has already added tremendous value to our business. For example, we’ve already created a new Claire’s language with clarity about how the same words can mean different things in different cultural contexts. We have also been able to give each other permission to check these potential misunderstandings. As we build Claire’s into an international business, I have no doubt we’ll be using their help again, this time, to get the Americans to understand non-Americans.”

Beatrice Lafon Group CEO, Claire’s Accessories

“Allyson’s knowledge and understanding of international retailing was underlined by her specialist panel at the 2022 World Retail Congress where she not only recruited a first class panel of retailers which she then expertly moderated leaving the audience of senior retailers with clear takeaways and insights.”

Ian McGarrigle CEO, World Retail Congress
