CHICAGO — Anacostia Rail Holdings has appointed Aimee Nolan as chief legal officer, the company announced today (Jan. 7).

Nolan will oversee legal, compliance, governance, and risk functions. She most recently was general counsel at Zoro Tools Inc., a subsidiary of W.W. Grainger, and had previously spent 25 years at W.W. Grainger, most recently as vice president and associate general counsel. There, she advised on tech and e-commerce matters, data protection and security, crisis management, global sourcing, mergers and acquisitions, intellectual property, procurement, regulatory compliance, and risk management.

She joins Anacostia as Mark Sidman, general counsel and corporate secretary, prepares to retire on March 31, 2026. Since joining Anacostia in 2013, Sidman has helped guide the company through sustained growth and reinforced a strong foundation of governance and integrity, the company said.

“Mark’s steady leadership and counsel have helped shape who we are today, and we are deeply grateful for his many contributions,” Peter Gilbertson, CEO of Anacostia Rail Holdings, said in a press release. “As we look ahead, Aimee brings the strategic mindset, operational discipline, and experience needed to help ARH scale responsibly and advance our mission in the years to come.”
