Tresart Gallery: A Personalized Approach to Art Advisory Services

Miami— January 8, 2023 — As we step into the new year of 2024, Tresart reaffirms its dedication to supporting our clients, colleagues, and community in navigating the ever-evolving world of art collection management. Our commitment extends beyond the ordinary; it is a promise to enhance your engagement with art, ensuring that each collection reflects your personal taste and aspirations. Join us as we embark on a journey of unparalleled collaboration, creativity, and connection.

Established in the vibrant art hub of Miami in 2000, Tresart Gallery, led by Antonio de la Guardia, has proven itself as a knowledgeable Art Advisory standing the test of time. Specializing in the secondary market, Tresart focuses on established contemporary and modern international artists. Over our impressive 23-year journey, the gallery has played a pivotal role in shaping public and private collections, marked by our commitment to transparency, discretion, and the fostering of enduring relationships.

At the core of Tresart’s success lies Antonio de la Guardia’s distinctive approach to the art business. Recognizing the paramount importance of relationships, Antonio shifted the gallery’s focus to advisory services in 2019, transforming its physical presence from a traditional white-cube gallery to a more intimate setting—a private-viewing art loft. This shift embodies our commitment to creating an environment where art and ideas can be comfortably shared, inviting clients and peers to explore the diverse world of art away from traditional gallery settings.

With over 25 years of involvement in the art world, Antonio’s expertise goes beyond providing astute advice and sourcing artworks; it extends to creating and sustaining an extensive network of international collectors, art dealers, and galleries. Antonio’s deep appreciation for art and understanding of the ever-evolving market have significantly contributed to shaping collections in the United States, Latin America, Hong Kong, and beyond. Through Tresart, Antonio is dedicated to fostering lasting relationships with clients by helping them navigate the intricacies of the art market, always keeping their best interests at the forefront.

Gallery Manager Marlen Batista, who joined Tresart in July 2020, has injected a fresh management strategy. Focusing on day-to-day gallery operations and enhancing customer relations through data-driven analysis, Marlen’s passion for the arts, combined with her background in business management, positions her as a valuable resource for Tresart’s clients as they grow their art collections. Her client-focused approach goes beyond commercial transactions, offering invaluable support for the gallery and its patrons in every fine art endeavor.

Tresart Gallery stands out not only for its excellent service but also for its commitment to creating a personalized and inviting space where art enthusiasts can explore, learn, and build meaningful connections. With Antonio de la Guardia’s seasoned expertise and Marlen Batista’s innovative management, Tresart continues to redefine the art advisory experience, providing a unique blend of art appreciation, market insight, and personalized service to its discerning clientele.
