About Us

Our People

Landau is Different

We know that what makes us different isn’t what we offer our clients, but who. As a 100% employee-owned company, we are informed by a deep pride of ownership in everything we do. With 67% of employees owning direct shares in the company, we are more than a staff, we are employee owners. We are invested in our clients, our projects, our team, and ourselves. Landau’s ownership model lends to the powerful dynamics of transparency and shared voice. In this way, we retain the right people because they feel valued and relevant. That’s what makes Landau different.
