  History

2025: Sundance, established as a Native American- and Woman-Owned Small Business, is now a premier environmental consulting, conservation, compliance, and remediation firm. Having maintained a steady and controlled growth, Sundance has more than 95 professionals bringing diverse experience and broad technical skillsets to nationwide project execution. Sundance’s interdisciplinary expertise includes archaeology, biology, botany, ecology, engineering, geology, geographic information systems, hydrology, toxicology and risk assessment, and a variety of other technical disciplines associated with renewable energy, compliance, planning and permitting, remediation, and environmental conservation and consulting.

In 2024, Sundance was acquired by True Environmental, enabling Sundance to provide an expanded depth of resources, including enhanced capability and service offerings, through our True platform partner firms. Together, the True family of companies comprise more than 700 employees, providing the complete scope of Environmental & Engineering Services focused on coastal resiliency, planning and environmental permitting, water and wastewater, clean energy, hazardous materials, remediation design, and regulatory compliance services.

2005: Sundance’s founder, September Myres, started Sundance to provide her client’s solutions to environmental issues resulting from Department of Defense (DoD) activities on Tribal lands. Prior to 2005, Ms. Myres worked for several environmental organizations supporting the US Army Corps of Engineers (USACE), Pueblos of New Mexico, and Native Alaskan Villages under the Native American Lands Environmental Mitigation Program (NALEMP). Through this experience, she gained expertise in bringing together culturally diverse organizations to provide environmental solutions while meeting the needs of multiple stakeholders. Ms. Myres’ success led to consecutive NALEMP contracts each year since 2005, as well as many other contracts with the USACE, other DoD agencies, the US Department of Agriculture, the US Department of the Interior, and many other federal and state agencies, as well as local agencies and commercial and private clients.
