Summit School Services

Summit School Services LLC, formerly known as National Express LLC (NELLC), is a premier provider of student transportation services across North America. Headquartered in Lisle, Illinois, the company operates a comprehensive network of school busing and transit solutions, serving hundreds of school districts and transporting over 1.3 million students daily. The organization underwent a significant rebranding in 2025 following its acquisition by I Squared Capital, an independent global infrastructure investment manager. This transition marked a new chapter for the company, which had previously operated as the North American subsidiary of Mobico Group (formerly National Express Group, PLC).

The company's operations are conducted through several well-established subsidiary brands, including Durham School Services, Stock Transportation, and Petermann Bus. These entities provide safe, reliable, and efficient transportation services, leveraging a fleet of more than 22,500 vehicles. Summit School Services places a strong emphasis on safety and operational excellence, utilizing advanced technologies such as the Lytx DriveCam® system, Zonar® electronic vehicle inspection tools, and its proprietary COMPASS scheduling platform. The company is also committed to innovation, recently launching 'Catalyst', a technology hub designed to integrate future-ready solutions into its fleet operations. With a workforce exceeding 10,000 employees, Summit School Services continues to be a leader in the student transportation industry, dedicated to connecting students to education through safe and dependable service.
