About Us

Sam McCahon

Established in 1997, McCahon Law has quickly become a leader when it comes to representing clients in a number of areas. Our clients range from large, multinational firms to small, disadvantaged businesses. Located in Washington, DC, we are an intensely focused law firm, so we limit the scope of our representation to our core competencies: government contracting, due diligence inquiries, combating human trafficking, and corporate compliance.

We believe that leadership is not derived from reading about what others do, but it is established from doing the things that others seek to emulate. Our firm has chosen our areas of practice based on our ability to lead these fields. No matter what case we are working on, we are always at the forefront with boots on the ground.

It is this mentality that distinguishes us. Because of our background, we have a unique perspective that results in an enhanced quality of services.
