A word from the managing partners

"Backed by nearly 70 years of expertise, we cultivate an unwavering standard in every file entrusted to us.

Our commitment rests on the stability of our teams and attentive listening at every moment.

Anticipating your needs to enhance your patrimony remains our priority, while preserving the relationship of trust that is our true strength."

Gérald & Thierry Rosset


Our values

Our profession is built on three inseparable strengths. They embody how we work every day — close to each person, and over time.

Rigour

A proven method and attentive follow-up for every file.

Our decisions are explained and shared, our deadlines and commitments kept : the quality of our service is built on day-to-day precision.

Closeness

Three agencies across Western Switzerland, with human and approachable teams.

A lasting presence on the ground : we stand close to every tenant, condominium owner or owner.

Sustainability

A responsible and environmental approach, rooted in our heritage.

Thinking real estate for the long term : enhancing properties over time, anticipating technical needs and innovating in the service of longevity.


Our commitments

Our profession entails strong responsibilities — towards those who trust us, towards the properties entrusted to us, and towards the environment in which we work.

Our quality approach has been ISO 9001 certified since 2014.

The Quality Management System deployed across our agencies ensures the reliability of every service, the follow-up of files and the continuous improvement of our processes.

An active member of USPI and the Western Switzerland real estate chambers, we uphold demanding shared standards within the profession.

This involvement enriches our practices and ensures compliance with an ethical framework recognised across the profession.

Aware of ecological challenges, we are actively committed to energy savings and the energy transition.

Our technical unit leads the energy renovation of the buildings we manage and advises owners and condominiums on the solutions to implement.
