Thomas Reinshagen
Spear’s Review
Thomas Reinshagen is a former senior director at Sotheby’s in Zurich, where he led the sale of art and luxury goods for clients across Switzerland. Now working as an independent broker, he continues to provide similar services on a private basis.
‘Clients would come to me with art, or wine or car collections, and I would arrange the authentication and auctions. It was a very broad brief that I had. What I did at Sotheby’s I now do privately with my own company,’ he tells Spear’s.
Reinshagen has a network of authentication and valuation specialists that he works with, from generalists for lower-value assets (he usually deals with lots worth between 50,000 and several million Swiss francs) to specialists, sometimes working with academics for very rare paintings.
‘Because I am independent and international I can work with galleries, auction houses and private dealers. I make a proposal to the client and ensure that the valuation is correct and the client gets the best deal,’ he says.
