About

Tresart was founded in Miami in 2000 and under Antonio de la Guardia’s leadership, the gallery specializes in the secondary market with a focus on established international artists, both modern and contemporary. In over 20 years, Tresart has played a key role in the development of numerous public and private collections, sourcing artworks of the highest quality and sustaining long-lasting relationships with a commitment to transparency and discretion.

Understanding that relationships are the most important aspect of the business, Antonio de la Guardia adapted Tresart’s business approach to focus on advisory services and moved his practice from a white-cube gallery to a more personal setting, a private-viewing art loft. 

Antonio de la Guardia and his team welcome clients and peers to Tresart’s art loft located in Miami’s Wynwood district, a space where art and ideas can be shared in a comfortable and inviting environment. To schedule a visit click here
