About WDH Advisory

WDH Advisory helps CEOs and leadership teams modernize operations, accelerate AI adoption, and improve performance at scale. We blend strategy, operating-model design, and hands-on execution to drive meaningful, measurable improvements in how organizations run.

As the Founder of WDH, my background includes global leadership roles as COO of R/GA and Chief Transformation Officer at Havas, where I led enterprise operations, delivery, production, commercial discipline, and AI workflow implementation across large, complex networks. I focus on building systems and ways of working that create clarity, accountability, and scale.

My approach is grounded in industry-leading best practices — including co-authoring the 4A’s Agency Operations & Business Transformation (AOBT) Standard and co-chairing the 4A’s AOBT committee shaping modern delivery, PMO design, and operational transformation across agencies.

Real transformation requires more than one perspective, it requires the right talent at the right moment.

Access to proven senior PM, operations, and transformation talent .

I bring a deep, global network of operators, program managers, workflow specialists, and change-management leaders, many of whom I’ve worked with directly. This allows me to assemble cross-functional teams quickly, tailored to the specific needs of each engagement: whether operational redesign, PM discipline, AI-enabled workflows, or enterprise-wide change management.

Every engagement is built around precision, accountability, and results. WDH Advisory exists to help organizations move faster, operate smarter, and scale confidently into the AI-enabled era.
