What TDM Specialists does

TDM Specialists is a private California-based professional services firm that provides transportation demand management (TDM) planning and commuter program implementation for real estate developers, employers, property owners, and government agencies. The firm develops TDM plans, parking management and traffic mitigation plans, pre-development mitigation assessments, and sustainable mobility programs designed to reduce vehicle trips, parking demand, and emissions, and to support project entitlement in jurisdictions that require TDM compliance. It also implements and manages on-site commuter programs, with practitioners acting as an extension of client staff to deliver commuter concierge services, employee outreach, and ongoing program management.

The company's commercial offering is structured around two core services, TDM Planning and Commuter Program Implementation, supplemented by consulting support and a reciprocal partnership with Hexagon Transportation Consultants, through which TDM Specialists provides commuter programs while Hexagon delivers CEQA-compliant traffic, parking, and bike/pedestrian studies. Revenue is generated through quote-based professional services engagements rather than productized pricing, and the firm maintains offices in the Bay Area (San Mateo, Santa Clara, San Francisco, Contra Costa, Alameda) and Sacramento/Yolo regions. No proprietary technology platform, software products, or AI/ML capabilities are publicly disclosed.

TDM Specialists was founded and led by Elizabeth Hughes, President and Principal TDM Planner, whose more than 20 years of industry experience and client relationships constitute the central asset of the firm. The company has been acquired by Galloway, a strategic operating company, and now operates as a Galloway specialty service line branded 'TDM, a Galloway Company,' with Elizabeth Hughes continuing as President. Headcount is reported at 1-10 employees, and there are no disclosed funding rounds, patents, or AI capabilities.
