Brian DiMarino Expands Role to Chief Commercial Officer
February 12, 2026
Chestnut is pleased to announce that Brian DiMarino has expanded his responsibilities to include Chief Commercial Officer, in addition to his role as Chief Operating Officer.
Brian joined Chestnut in September 2025 as COO. Since then, he has played a central role in overseeing land acquisition and planting operations for our fourth planting season and in managing our growing afforestation footprint across the Southeast. Under his leadership, the project has expanded to more than 48,000 acres—an area comparable to Acadia National Park.
In his expanded role, Brian will draw on 19 years of experience at JPMorgan Chase, where he most recently served as a Managing Director and the Deputy Director of Global Sustainability, Strategy, and Operations, leading carbon purchases for the bank. His perspective from the buyer’s seat, experience driving carbon‑neutrality progress, and global leadership in GHG abatement and resource management brings vital expertise to Chestnut as we advance high‑quality, nature‑based carbon removal.
Brian’s leadership will undoubtedly help further strengthen our partnerships with global organizations and support them in achieving aggressive decarbonization and net‑zero goals.
