Muir transitions to CEO after serving as Chief Operating Officer, a position that placed her at the heart of the network's recent international development. Since taking the reins, she has conducted a comprehensive consultation with member firms spanning 119 countries. These internal discussions were designed to identify shifts in the accounting and advisory profession, specifically focusing on technological transformation and the rising demand for sophisticated advisory services.

Moving beyond the planning phase, Muir is now shifting the network's focus toward execution. Her strategy emphasizes strengthening international connections and supporting firms as they adapt to evolving client expectations. Despite these structural shifts, Muir insists that her primary objective is not to overhaul the organization's identity, but rather to unlock its latent potential. She aims to leverage the existing foundation of 37,000 employees while preserving the entrepreneurial independence that defines Moore’s culture.
