Our Approach To Business
Business Model
Our company name reflects our business model. Corporate management and infrastructure don’t provide direct support to our clients. Our employees do. If we attract and retain the best employees in our industry, we will be successful. If we fail to provide a quality workforce, nothing else matters. We achieve our purpose and our business success through hiring and retaining the very best employees in our industry.
Corporate Stability
Our ability to maintain consistent, predictable operations supporting our nation’s servicemen and sound financial position ensures long-term success. Sale of a company is potentially very disruptive to both clients and employees and might dilute the focus on serving the long term interests of our nation, government clients, and employees. Therefore we acted, through legal restrictions on ownership and sale of company stock, to prevent the sale of the company to outside parties. This facilitates stability of ownership for our clients and our employees and fosters a focus on long term value.

Purpose And Focus
Conflicts Of Interest
We provide program management support and SETA (Scientific, Engineering, and Technical Assistance) support services to the government. As a trusted agent for the government, we will not perform prime system development or be a subcontractor to a prime system developer. Roles on prime system development contracts are avoided because such roles would potentially create a conflict of interest.
