TRANTER–SINNI GALLERY

Tranter–Sinni Gallery is an appointment-only gallery platform with locations in Miami (Wynwood), Las Vegas, and Marbella, Spain, operating exclusively with private clients and private collections. The gallery maintains an intentionally limited exhibition program, presenting four curated exhibitions per year, allowing for depth, scholarship, and a highly personalized collector experience.

Founded in 2009 with its first gallery platform in Toronto, Canada, Tranter–Sinni Gallery specializes in secondary-market works by Modern, pre- and post-war, and contemporary European and American artists. Each exhibition is conceived as an immersive, museum-level presentation, emphasizing historical significance, provenance, and cultural impact.

The gallery has recently expanded to include a dedicated Forensic Art Department, developed in collaboration with expert partners at INSTITUT d’ART CONSERVATION et COULEURS (France), providing advanced expertise in authentication, material analysis, and conservation.

Tranter–Sinni Gallery offers bespoke advisory and consulting services, guiding collectors through acquisition, collection building, valuation, and legacy planning. Working closely with estates, foundations, institutions, and international collectors, the gallery is committed to presenting only works of the highest quality, rarity, and historical importance.

Each gallery location functions as a private viewing space, designed for discreet acquisitions, curated installations, and scholarly dialogue—serving collectors who value connoisseurship, trust, and access over volume.
