Gladstein, Neandross & Associates

What Gladstein, Neandross & Associates does

Gladstein, Neandross & Associates (GNA) is a North American consulting firm founded in 1993 that specializes in market development for low-emission and clean transportation. The firm advises transportation sector organizations — including fleets, government agencies, and commercial/industrial entities — on fleet electrification, alternative fuels, infrastructure assessment, regulatory compliance, and sustainability strategy. The company has been absorbed into TRC Companies, Inc. (legal name of the operating entity), which itself was acquired by WSP Global, integrating GNA's clean transportation consulting practice into WSP's broader engineering and infrastructure services portfolio. Branding has consolidated from gladstein.org to trccompanies.com, with the firm now marketed as the Clean Transportation Consulting service line under TRC/WSP.

The firm's product surface is overwhelmingly services-oriented: advisory and consulting engagements delivered through direct enterprise sales to government and large buyers (phone + inquiry form), supported by a multi-channel thought-leadership marketing apparatus spanning LinkedIn, Instagram, email newsletter, webinars, and a white-papers/resources hub. The only named software product in the portfolio is Lemur™, a TRC Companies offering rather than a GNA-original product, and no proprietary technology stack, AI/ML capability, or platform architecture is disclosed in the available evidence. Revenue mechanics follow a professional services model — billable consulting engagements with pricing not publicly disclosed — and the practice relies on the reputational and regulatory expertise of named principals (CEO Erik Neandross, founder/President Cliff Gladstein, Senior Director Nate Springer) to win enterprise and government mandates.

Operating jurisdictions center on the United States (Santa Monica HQ, additional office at 21 Griffin Road North, Windsor, CT 06095), with no asserted global footprint at the standalone practice level; global reach is now derived from WSP's worldwide engineering platform. The firm employs 11-50 people, is privately held with no public ticker, and has no disclosed funding history, regulatory actions, patents, awards, or named customer logos on record in the supplied material.
