Marie-Hedwige El Khoury (Forvis Mazars Luxembourg) : Agility through proximity and precision
Marie-Hedwige El Khoury, partner and head of accounting & outsourcing services at Forvis Mazars Luxembourg, explains how agility, global expertise, and innovation help the firm support clients amid uncertainty and digital transformation. Interview.

How do you stay agile and responsive when clients face uncertainty?
One of the foundations of Forvis Mazars in Luxembourg is our close relationship with our clients and the assistance we provide from A to Z, in order to meet their objectives and expectations while providing a personalised approach ‘The right fit’. In uncertain times, this proximity enables us to work together efficiently and react with agility to tackle and overcome potential challenges serenely and smoothly.
Our agility and responsiveness also stem from several key practices embedded in our way of working:
-
We work in sprints — short, outcome-driven cycles (typically two‑week sprints) — which enable us to rapidly adapt to shifting circumstances.
-
We prioritise high-value tasks over low-effort activities, ensuring that our resources remain focused on what matters most to clients.
-
We embrace change through continuous feedback, regularly reviewing deliverables, welcoming new information, and adapting our work accordingly.
-
We leverage deep expertise across wide-ranging fields, allowing us to respond with precision and confidence regardless of the complexity involved.
Our management team, along with the teams that support it on the ground, benefit from permanent and transparent contact with our partners. This enables us to establish lasting relationships founded on trust, expertise, quality, and responsiveness. At Forvis Mazars, we are redefining collaboration and helping our clients prepare for what’s next with confidence.
What does "global expertise, local presence” look like in your day-to-day work with clients?

Are there any upcoming changes or projects you are particularly excited about?
We are particularly excited about how artificial intelligence and the growing demand for operational efficiency are reshaping client expectations and our own service delivery model. These shifts are already driving concrete changes in the way we work and serve our clients, notably through: The integration of IA into our core services: We are embedding AI into our audit, tax, and advisory workflows to enhance data analysis, automate repetitive tasks, and increase audit coverage and accuracy without compromising quality. This allows our teams to focus on higher-value insights for clients. The expansion of outsourcing and co-sourcing solutions: Clients facing cost pressures and talent shortages are increasingly turning to us for outsourced solutions in accounting, compliance, and operational reporting. Our Luxembourg office is scaling its Business Services and Tech-Enabled Managed Services in response. The pursuit of an efficiency-driven client partnerships: Across sectors especially financial services we’re partnering with clients to simplify processes, reduce duplication, and leverage technology platforms for smarter compliance and reporting. This aligns with Luxembourg’s broader trend toward digital transformation in a high-cost, talent-competitive market.These developments reflect our ambition to lead with innovation, help clients do more with less, and position Forvis Mazars as a trusted, forward-looking partner.
