Property Expert

Guy-Claude Piot


In 1990, Guy-Claude Piot began his professional career as an apprentice draftsman in an architectural firm in Echallens. In 1995, he left the firm and took the opportunity of a gap year to visit Australia and New Zealand.

On his return, he undertook training in IT and then changed direction, in 1998, as a property manager in a Lausanne estate agency.

In 2000, he joined a major bank in the ‘Property Risk Analysis’ department as a property manager where he carried out the valuation of specific properties: a great introduction to the world of valuation.
In 2002, the service merged with the appraisal service; it was at this point that he began to practice property appraisal on a daily basis.

He took advantage during this time to consolidate his skills by successfully obtaining his federal diploma of expertise in property valuation at the USPI, in 2004.

In 2005, he then decided to continue his career and exercise his new skills in a private appraisal office where he had the opportunity to work for various types of principals, in particular individuals, notaries, lawyers, for courts, banks and insurance companies, as well as for several pension funds and property funds.

Guy-Claude Piot joined the Swiss Chamber of Experts in Property Appraisals (CEI) in 2006.

In 2010, he wanted to change horizon to join a large insurance company in Lausanne, where he became responsible for valuation for French-speaking Switzerland. He perfected his knowledge of the French-speaking Switzerland market, particularly in the neighbouring cantons including Geneva, Valais, Fribourg, Neuchâtel and Jura.

He also served as an expert in the oral examinations of the Federal Diploma of Expertise in Property Valuations for three consecutive years between 2014 and 2017.

After seven years spent estimating for the mortgage department, Mr Piot joined Cogestim in 2017 to take over the role of group expert and also join the Project Management department with Mr Pierre Aguet, director of the company.
