Founded in Medellín. Growing from Miami.

Antonia, known as Mila in close circles, is a serial entrepreneur with ventures spanning luxury property development and art. She was a professional real estate investor for many years before entering the art industry.

Today she is the creative director of Mido Gallery, alongside the other business ventures she leads.

Jonathan Marin is an international commercial leader with more than 15 years of experience across technology, software, robotics, and high-growth businesses. Alongside his role at Mido Gallery, he continues to serve as a Chief Commercial Officer, leading commercial strategy, market development, partnerships, and revenue growth within the technology and robotics sectors.

His professional journey began in London, where his passion for art first took shape more than 15 years ago. Surrounded by one of the world's most influential cultural capitals, Jonathan developed a lasting appreciation for artists, galleries, collecting, and the way exceptional works can create a deeply personal connection with the people who live with them.

Throughout his career, Jonathan has built and led commercial strategies across international markets, working in complex, high-value sales environments where trust, negotiation, human behavior, and long-term relationship building are essential. His experience as a CCO gives him a distinctive perspective within the gallery world, combining commercial discipline with a genuine understanding of how people make important purchasing decisions.

At Mido Gallery, Jonathan leads collector development, international sales, strategic partnerships, and the commercial positioning of artists and significant works. His approach is highly personal: understanding the collector first, then helping connect them with works that resonate with their taste, story, and long-term vision.

For Jonathan, the most meaningful acquisitions happen when there is trust, knowledge, emotion, and a genuine connection between the collector and the work. His role at Mido Gallery brings together two important parts of his life: more than 15 years of international commercial leadership and a passion for art that began in London and continues to shape the way he works with artists, collectors, and the gallery today.

Judith Rosales is a gallery and fair specialist and a familiar, trusted face to many of the artists who show with us. A close friend of Mila, she has supported her and the gallery from the very start.

Her own story is one of resilience. Judith built her path with determination, studying through night school and community college and working her way up from paralegal to office manager at a law firm. She brings the same drive, and a real gift for caring for people, to every gallery and fair project she takes on with us.

From the gallery to the fair floor, Judith helps our artists and collectors feel welcomed and looked after.
