Arjan de Roy, Vice President and General Manager Germany / Austria, Sirona Dentsply

„Our executive team worked closely with Matthew over the course of two years, addressing critical topics such as team structuring & reporting, performance analysis, and goal setting. Matthew played a key role in keeping the executive team aligned and focused, breaking down complex topics and in some cases disagreements into manageable and solvable slices. He did this by understanding the business deeply and understanding the personality of each executive stakeholder. Matthew’s contributions helped the team get through critical issues and come away with a solid plan, and his ongoing sessions helped to keep track of what we agreed upon and how we were tracking to the goals. As an executive coach, Matthew was instrumental in the development of our executive team during a period of rapid growth, and I would recommend his services to any fast-growing team that needs to ensure alignment and thereby better performance.“
