Prestige & Commercial Divisions

Crafting the Exceptional with Experience and Vision

The creation of our Prestige Division reflects a clear ambition: to offer a real estate experience that exceeds expectations. It means listening, anticipating, advising, and guiding clients through the most delicate transactions. Each mandate is approached as a unique project — carefully considered, discreetly managed, and attuned to the right tempo. This posture is no accident: it stems from a deeply rooted culture. From day one, we have embraced a tailor-made approach, grounded in in-depth local knowledge, proactive guidance, absolute transparency, and meticulous attention to detail.

A Culture of Hospitality and Refined Essentials

Within our Maison Immobilière, every client is welcomed in a confidential and structured setting, designed to encourage meaningful exchanges and clarity of process. Everything is created to enable calm, constructive dialogue and a long-term relationship. At the heart of this structure, the Prestige Division brings together experienced real estate professionals and operates with a spirit of continuous improvement. It sharpens our methods, refines our expertise, and opens new perspectives. Let us now introduce the professionals who bring this vision to life.

Manon Rollet | The Intuition of a Space, the Precision of a Conversation

Trained early in the dynamics of the local market, Manon Rollet quickly made her mark in the high-end residential sector. From the outset, she approached each mandate with relentless energy and a genuine passion for client relations. Today, she navigates the Prestige segment with fluency — sensitive to flows, lifestyles, and spatial clarity. Manon values authenticity, honest dialogue, and rigour in execution. For her, every mandate is a concrete mission built to last. Her availability, reactivity, and 360-degree experience shape a comprehensive, structured, and vibrant service. A true high-end specialist, she blends love for real estate with an acute attention to detail and the ability to forge sincere, well-structured relationships. Having worked across all aspects of brokerage, she brings both a holistic vision and hands-on expertise to every interaction.

William Cassin | The Art of Adaptability in Service of Precision

With over twenty years of experience in wealth management and prestige real estate, William Cassin approaches brokerage as a refined craft — at the intersection of technical precision and emotional intelligence. He advises high-net-worth international clients through sensitive and often off-market transactions, anticipating every need with calm and method. Comfortable in diverse social and cultural environments, he adjusts his approach, pace, and posture to the moment. His strengths lie in reactivity, reliability, and the ability to perceive deeper stakes beyond the property itself. With a service-driven mindset honed over two decades, William operates seamlessly in demanding contexts. A strategic asset to the Prestige Division, he builds grounded, enduring relationships in line with expectations of discretion and excellence. He embodies the Geneva way: discreet, cosmopolitan, detail-oriented.

Stéphanie Antille-Gaumann | Precision Shaped by Commitment

As Head of Residential & Prestige Lettings and company proxy-holder, Stéphanie Antille-Gaumann is a pillar of our Maison, having supported clients for over twelve years. With a dual background in hospitality and business management, she has turned her instinct for human relations into a lever for excellence. She combines in-depth knowledge of the Geneva market with rare listening skills, allowing her to quickly identify and meet highly specific client expectations. Her approach is clear: active listening, precision, and focused support. Stéphanie orchestrates the flow between residential and high-end portfolios with rhythm and finesse. Each situation calls for sensitive interpretation; each client, a bespoke response. In a constantly moving environment, she remains a reliable and committed anchor — for clients and colleagues alike. Her style is to structure without rigidity, extend without excess — a refined form of service rooted in trust and experience.

Commercial Real Estate | Territorial Expertise and Strategic Advice

Our Commercial Real Estate Division forms a core pillar of our new structure. Led by Stéphanie Antille-Gaumann and Daniel Sousa, it supports businesses, investors, and owners in acquiring, developing, or divesting commercial premises, income-generating properties, and mixed-use assets. Active in both Geneva and Vaud, our team brings in-depth territorial knowledge and precise negotiation capabilities. We also assist with market entry strategies, asset analysis, and operational projections. Each project is approached holistically, with the same standards of excellence as our residential mandates.

A Forward-Thinking, Committed Dynamic

2025 marks a pivotal year in PRIVALIA’s journey. We are expanding our teams, structuring our expertise, and integrating new technological tools — including artificial intelligence — to streamline our processes and enhance responsiveness. These developments reflect a coherent strategy: to better understand, better support, and offer a working environment that is ever more precise, agile, and aligned with specific expectations. Through our Prestige and Commercial Divisions, we affirm our position: more than just an agency, PRIVALIA is a trusted partner, able to support life projects and investments with care, consistency, and discretion. And our story continues. In June, a major announcement will extend this path — a step conceived with intent, true to the spirit of our Maison: to structure, refine, and move forward.
