Expert guidance on a complex waterfront development

Michelle O'Brien provided exceptional counsel on the environmental permitting for our waterfront property in Boston. Her 35 years of experience, particularly in land use and zoning, were immediately evident. She navigated complex regulations with authority, and her litigation background gave us great confidence. The process was smooth, though communication occasionally had brief delays during peak periods. Her recognition in environmental law is well-deserved. We achieved a favorable outcome and would recommend her expertise for any sophisticated development project.
