I am a seasoned attorney and policymaker with extensive experience in transportation, environmental, and energy law. Over my career, I have represented or led in federal agencies, having served as the General Counsel for the United States Department of Transportation and Director of Environmental Programs for the Colorado Department of Public Health and Environment. I’ve also represented state departments of transportation, local governments, transportation agencies, and private entities across the country. My practice has focused on navigating complex federal and state regulations to deliver innovative solutions for infrastructure, sustainability and safety challenges. Known for my strategic counsel, I have played a pivotal role in advancing policies and projects that balance development, environmental stewardship, and community needs, including implementation of the Federal Infrastructure Investment and Jobs Act of 2021 (also known as the Bipartisan Infrastructure Law) renewal of the Moffat Tunnel lease and provision for passenger rail access in Colorado, and development of and Colorado’s Greenhouse Gas Reduction Roadmap.
Prior to rejoining the firm, John was a Senior Advisor at the Colorado Department of Transportation from 2023-2025, where he advised the Executive Director and Governor on rail and transit issues and served as the Governor’s Chief Negotiator for the renewal of the 99-year Lease of the Moffat Tunnel under the Continental Divide. The Governor appointed John to be a member of the Front Range Passenger Rail District Board and Colorado Rail Safety Industry Advisory Committee.
John was confirmed by the U.S. Senate as General Counsel of the U.S. Department of Transportation in May 2022, after serving as Deputy General Counsel since January 2021. In his role, he collaborated with the Department’s senior leadership and oversaw a legal team of nearly 500 attorneys, addressing complex legal and policy issues across all operating administrations within the Department. The scope of his legal work and program oversight included implementation of the IIJA (also known as BIL), rulemaking, grant and loan programs, operations, enforcement, permitting, environmental, civil rights, consumer protection, accessibility and other issues affecting all modes of transportation. John has also served as Director of Environmental Programs at the Colorado Department of Public Health and Environment (CDPHE). In this capacity, he oversaw divisions responsible for air quality, water resources, waste management, and environmental health and sustainability.
