Our story

Three pillars,
one conviction

Born of a deep conviction: that real estate is, above all, a human endeavour. Our agency was built on three pillars: excellence of service, closeness to our clients and an intimate knowledge of the local market.

We operate across the Nendaz and Sion region, for a main residence, a mountain chalet, a buy-to-let investment or a commercial property. Every file is handled with the same rigour and the same care.

Our team

Behind Alpinvest are people who love their profession, their region and their clients: property expertise, local knowledge and a sense of service at every step.

I had the chance to go on several viewings with Jonathan Frossard and, honestly, a very good experience. Jonathan is someone who is available, punctual and, above all, very pleasant. He knows Nendaz and the region's property market extremely well. He takes the time to answer questions and gives his honest opinion, without ever trying to push you into buying at any cost. I particularly appreciated the human side and being able to talk simply and openly during the viewings. You can tell he knows the properties he presents very well and genuinely loves his job. I wholeheartedly recommend Jonathan and Alpinvest Immobilier SA if you are looking for a serious real estate agency in Nendaz.

I first met Jonathan when he showed us a chalet we were interested in buying in 2018. He impressed us with his honesty and reliability. Always highly dependable and competent, he showed impeccable ethics. No doubt I would recommend him to anyone selling a chalet in the region.

Excellent experience working with Jonathan on the sale of our chalet in Haute-Nendaz. He worked quickly, professionally and with great dedication, and managed to sell within 3 to 4 months. Extremely responsive, he handled the negotiations with impressive skill. We recommended him to friends. Another sale within months. Our highest recommendation.

Jonathan is a very professional agent whom I warmly recommend. He guided us from the start through to signing, in every step. Always available and competent, he knew how to handle sometimes difficult negotiations while remaining neutral. Honestly, the sale was not straightforward and probably would not have gone through without him.

Jonathan was excellent. Extremely responsive, down-to-earth and highly trustworthy. The level of service and attention was simply extraordinary. He represented everyone's interests with care, fairness and transparency, and even introduced us to his trusted contacts. More than an estate agent: a friend and a partner. I warmly recommend him.

From the very start, we felt in very good hands with Jonathan. Everything moved quickly: in a short time he presented two potential buyers and managed the competitive situation very well. Within days the deal was done, and he then took care of all the formalities. We warmly recommend him for any property transaction!
