Nstone

Nstone

Nstone was founded in 2010 as a small business consulting engineering firm in Albuquerque, New Mexico. Don Lincoln, a registered Professional Engineer with a background in mechanical engineering and over 50 years in the commercial nuclear and Department of Energy sectors, serves as president. The firm's senior management includes Vice Presidents Lynnwood Dukes and Roger Hein, each with over 40 years at institutions including Sandia National Laboratories and the Army Corps of Engineers. The firm's service lines span Business Support & Analysis, ES&H Operations, Operations & Facility Management, Energy Management, and Project Management — all delivered to the facilities management and project management sectors. Nstone does not appear to operate as an investment vehicle; rather it is a government-services engineering contractor. The firm named Sandia National Laboratories as a key customer, noting a Small Business Supplier of the Year award from Sandia in 2019. No portfolio companies or co-investor relationships are disclosed. The company has grown from 2 employees at founding to over 50 as of 2026. Its sole disclosed office is at 2201 San Pedro Drive, Building 4, Suite 100, Albuquerque, New Mexico. No philanthropic structures or adjacent vehicles were identified. No recent operational events from the last 24 months were found in available sources. Nstone's structural distinctive is its concentration on government and DOE-related facilities contracts via a small business designation — a model that relies on senior management's long-tenured relationships with Sandia National Laboratories and other federal entities. This positions the firm less as a typical family office or investment firm and more as a specialized professional services provider aligned with federal infrastructure and energy management.
