SCMC, LLC (SCMC) offers a full range of environmental services capabilities and solutions, program management, construction management services, and technical staffing, to federal, state and local governments and within the private sector.

We are a Tribally owned, Native American 8(a) certified Small Disadvantaged Business, and while this status provides unique contracting advantages to our federal clients, our experience and qualifications and strong partner relationships differentiates us from the competition.

SCMC is owned by Seneca Holdings, LLC, which is owned by the Seneca Nation of Indians. This provides SCMC the strength to meet the ongoing requirements of our clients in ways not normally available to small businesses.
