After graduating from Harvard University with a degree in Art History, he started working at Christie's in 1983. He rose to become Director of European Furniture at Christie's USA, overseeing a team of 15 people and organizing up to 20 high-profile auctions a year.
In late 1995, Christie's sent him to Paris to head the Furniture Department and to help direct the expansion of the French operations in advance of the opening up of the French market to foreign competitors.
In 1997, after nearly 15 years in the auction business, Iselin set up his own company in Paris and has steadily expanded its operations, working with clients in Europe, Australia and North and South America.
In 2014, he moved his business to London in order to take advantage of the capital’s increasingly dynamic position at the centre of the international art market.
Drawing on his considerable experience accrued over the course of many years in London, New York and Paris, Iselin is in the strongest possible position to help clients navigate the complexities of the market for English and European works of art. He has an acute understanding of the market and its many nuances, and has built and maintained trusting long-term relationships with collectors and industry professionals worldwide.
