It’s not enough to possess an uncanny knowledge-base of materials, details and plants. We recognize that a strong determinant of our success is closely linked to the quality of the people situated at the core of what we do.



Mac Carbonell
Principal, Design Director

Several of the oldest trees on record grow on the grounds of Mac's childhood home, a historic farm & farmhouse situated at the bend of Brandywine Creek in Pennsylvania. All that was there nurtured his lifelong passion for, and evolving relationship with Nature.

Raised by a family of architects and horticulturists, he gained a deep appreciation for the arts and botany in his early life.

He received a BA in Photography at Yale and an MFA at the School of Visual Arts. 

As principal, Mac is Verdant's creative leader, consistently exploring and reinventing the thread between art, landscape and horticultural relationships, while relentlessly pushing the boundaries of conventional norms. Mac initiates and guides the creative process of each project, driven by an aesthetic of strict form and spatial planning and a refined framework highlighting the transportative qualities of plants in the landscape.
