Your leading real estate agency in the heart of the Aravis

For over 65 years, ATHERAC has been based in the heart of La Clusaz, where it represents far more than just a real estate agency — it is a historic and committed player in the resort. Through its three offices, located just steps from one another, ATHERAC supports its clients in all their projects: vacation rentals, co-ownership management, and real estate sales and purchases.

Proud of its local roots and deep knowledge of the Aravis property market, ATHERAC relies on a team of 30 staff members, most of whom are from the region, to offer support built on proximity, responsiveness, and professionalism.
Based in La Clusaz, and also active in Le Grand-Bornand, Saint-Jean-de-Sixt, and Manigod, the agency provides personalized follow-up tailored to the specificities of each micro-market, combining local expertise with a modern vision of real estate.

At ATHERAC, we know that every property deserves a strategy tailored to its nature and target audience.

A mountain region, a broad range of expertise

While La Clusaz and Le Grand-Bornand are iconic hubs of the Aravis mountain range, ATHERAC’s expertise goes far beyond these well-known resorts. We support your property purchase and sale projects across the region’s authentic mountain villages, including:

Saint-Jean-de-Sixt
Manigod
And also in areas rich in character and potential, such as: Entremont, Le Petit-Bornand-les-Glières, Thônes, Serraval, Les Clefs, Le Bouchet-Mont-Charvin, La Giettaz, and Flumet.

United by their mountain spirit, these areas offer a wide variety of properties — chalets, renovated farmhouses, village homes, and land — all in an authentic and unspoiled setting.

Enhance your property with our renovation service

We address a common challenge: properties in need of renovation, often overlooked due to poor energy ratings (DPE). By combining the purchase of an older apartment with our renovation support service, we offer a distinctive approach. Why choose our service?

Energy-efficient renovation of your property
Increased property value
Contemporary design
Turnkey support from start to finish

Invest with confidence in a renovation project and transform your property into a unique space that blends Alpine charm, comfort, and energy efficiency.

The management team

Founded in 1958 by the Thevenet family, ATHERAC has evolved with the times while staying true to its identity. In 2019, with the retirement of Patrick Thevenet — a prominent figure in La Clusaz real estate and son of the founder — the agency enters a new era. It is now led by a shareholder pact formed from within the staff, the result of a natural and solid succession.

Some of these executives have been with the company for over 25 years and possess intimate knowledge of the local market, properties, co-ownerships, and, above all, client expectations. This internal succession is a real strength: it guarantees the continuity of ATHERAC’s core values — proximity, excellence, and local roots — while bringing fresh energy.

Each business unit (rental, property management, sales) is now led by seasoned professionals, deeply committed, with a clear vision and a genuine drive for innovation in service of the clients. This collective, responsive, and passionate governance strengthens ATHERAC’s foothold in the Aravis like never before.

The agency’s history

1958 - Agency founded by Fernand Thévenet

Jacques RACHEL and Fernand THEVENET, two friends and comrades-in-arms during the Battle of Aiguille du Midi, joined forces to create the first real estate agency in La Clusaz. The agency started in a simple room located above the Rocher garage, at the entrance of this small village in Haute-Savoie.

1989 - Patrick Thévenet succeeds Fernand

At age 70, Fernand THEVENET passed the reins of the agency to his son, Patrick.

1998 – Start of vacation rental services

Creation of "Locathérac," a website exclusively dedicated to vacation rentals.

2019 – Agency takeover

Patrick THEVENET retired, and the ATHERAC real estate agency was taken over by the company’s management team.

ATHERAC’s three business divisions (sales, property management, and vacation rentals) are now led by an active shareholder pact composed of eight members who jointly participate in strategic decision-making.

2021 – Integration of Snow Lodge

The group strengthened its vacation rental offering with the acquisition of the SNOW LODGE brand, a specialist in high-end chalet rentals since 2009 in La Clusaz.

2023 – Affiliation with Christie's International

The Sales division joined the Christie’s International Real Estate network. This affiliation positions our agency as a leading player in the luxury market while benefiting from global resources and a worldwide network that enhance its appeal.

2024 – New Renovation Service

Creation of a turnkey renovation service designed for buyers wishing to enhance an older property while ensuring compliance with upcoming energy efficiency standards.

Today – Presence across the Aravis region

Thanks to our expanded team of sales professionals covering the areas of Grand-Bornand, Manigod, Saint-Jean-de-Sixt, Thônes, Entremont, Les Clefs, Le Bouchet-Mont-Charvin, Serraval, La Giettaz, and Flumet, we now offer you comprehensive and personalized expertise across a wide territory.

Our mountain real estate market expertise is set to expand to other municipalities, allowing us to provide even more complete and tailored support to meet your evolving needs in new Alpine areas.

A summer night in La Clusaz: the mountains in a different light

On June 28, La Clusaz experienced an extraordinary evening. To celebrate the Moonlight Stroll, the entire village was plunged into darkness: street lighting was turned off, shop windows were extinguished, and the streets were illuminated by candlelight. There were street art shows and wandering musicians everywhere
