Firm
Our Core Values
We are
competitive.

Our core values shape our conduct, drive our decisions, and determine who we are as legal professionals. Our core values define us, capture the unique nature of our firm, and distinguish us from others.

Our Value Proposition

We provide clients with the peace of mind that comes from working with skilled professionals focused on their specific legal needs with a history of providing effective, creative, and efficient solutions.

Focused
Focused

Unlike practice groups at some large, full-service firms where attorneys may split their time across various areas, each member of our team is dedicated solely to government contract law. Our focus provides us both a deep understanding of the unique challenges our clients face and extensive experience solving government contract law problems.

Effective
Effective

Our results are a testament to our effectiveness. Whether we are securing a contract award through strategic advice or the bid protest process, converting a termination for default through negotiation, summary judgment, or trial, or resolving any other claim, dispute or issue relating to the award or performance of a government contract, we provide solutions that help our clients succeed.

Creative
Creative

Our creativity is not a stroke of luck; it is the planned result of our experience, curiosity, and dedication to solving a client’s problem. Creativity is often the key to success, and we make it a priority in everything we do. This approach enhances our ability to develop innovative solutions that align with a client’s goals and solve complex legal problems.

Efficient
Efficient

Time is money, and we do not waste either. Like creativity, we plan for efficiency. We carefully evaluate issues and prepare and track budgets. We minimize delays and avoid unnecessary battles because the longer a problem is left unresolved, the more it generally costs to resolve it. This proactive approach not only saves time but also reduces costs, enabling us to deliver highly efficient solutions.

Our Team

We are dedicated attorneys and professionals who have credibility with the agencies our clients work with and the attorneys who represent them.

We take a mission-first approach to the problems our clients ask us to solve.
