Many appraisers may claim the expertise to
properly value a Camille Pissarro oil on canvas.

 

However, only a few have personally handled dozens of examples over decades at the leading auction rooms, and are intimately familiar with the major collectors and curators in the field.  They are keenly aware of which market participants are actively acquiring or disposing, and know them well enough to take their call…

These discrete market insights and relationships are only cultivated through lifelong apprenticeship, and are the signature capability of every member of our consulting team.

 

Each of our 40 art market categories is overseen by at least one former Senior Specialist or Department Head from Sotheby’s, Christie’s, Bonhams or Phillips.

Our network also includes

  • Former and current members of the Vetting Committees of the leading art fairs in Europe and the Americas

  • Former and current appraisers on the Antiques Roadshow in the US and the UK

  • Former curators and directors from major American and European museums
