First of all, I want to emphasize that Ms. Nicole Salamin received me very well when I wanted to sell my property. She is a person who knows very well where she is going to handle your file. Her statements are clear, and she knows the path to follow to successfully manage the entrusted business. An experienced person with great know-how in her profession or elsewhere. She is well acquainted with all the intricacies of her profession. A cultured person in more than one way. She can be trusted. Furthermore, I greatly appreciated her nature; she is a very pleasant woman with a very Valaisan spirit, willing and knows how to have humor when necessary. I keep an excellent memory of her. Best regards. Pierre Jaccard February 15, 2025.

Madame Alder is a very committed person and professional. She demonstrates great skills both in her relational and human attitudes as well as in her technical approach to sales. She stands out for her kindness, active listening, availability, punctuality, responsiveness, and her "solution" orientation! Her interventions were of high quality, demonstrating great respect for my private sphere, allowing me to entrust her with my full confidence! I can only recommend collaborating with Madame Alder.

In May 2024, I purchased an apartment through Duss Immo GmbH and was accompanied throughout the entire purchasing process by Mirjam Heller. The collaboration was very pleasant, professional, and trustworthy from the very beginning. I would particularly like to highlight her always accommodating manner as well as her excellent availability. She responded quickly and reliably to emails at all times, so that any open questions could be clarified promptly. Furthermore, she communicated all relevant information transparently and openly. I always felt comprehensively advised. Through her competent support and commitment, the purchasing process was efficiently advanced. I would like to sincerely thank her for the professional guidance, transparent communication, and excellent service. I can wholeheartedly recommend the collaboration.
