Our Desk
The people behind every lot.
Eight department heads. Sixty combined years on the bench. Every piece that reaches a catalogue passed through their hands.
Each category is led by a department head and supported by senior specialists. Between them, the panel carries experience from Sotheby's, Christie's, Phillips, the Patek Philippe Academy, the GIA, and RICS. The biographies below reflect the lead specialists you will work with when consigning or pursuing a lot.
