Behind the scenes


We find fulfillment in our work.

We take ownership of our own happiness. We’re happiest when we’re making progress toward our goals. We don’t do this because it’s fun, we do this because it’s important. We are committed to solving hard problems, working long hours and slogging it out when necessary.

We always get it done.

We are a trusted resource and ally for our clients. We stake our reputation on our work and stand behind our word. We don’t succeed until our clients do.

We expect leadership at every level.

Leadership is important in all roles, not just for management. Leadership means taking total responsibility for tasks, communicating up-and-down the chain of command, inspiring others, and proactively mitigating risks. Leadership is our highest calling.

We operate with humility & courage.

We ensure our ego does not get in the way of our work or relationships. We operate with humility and courage, honestly assessing our own performance by taking ownership of mistakes, and developing an achievable plan for success. We give each other kind, clear, specific, and sincere feedback when it’s the right thing to do, even if it’s difficult.

We embody professionalism.

We are calm and unwavering in all circumstances. Where others have their resolve shaken, we remain steadfast. Our work, communication, and actions are polished, so our clients always feel confident and rest easy knowing that they are on the path to success.

We win as a team.

If the team fails, everyone fails, even if a specific member or an element within the team did their job successfully. We don’t seek to attribute wins to individual performance but instead celebrate wins as a team.

We insist on the highest standards.

Yesterday isn’t good enough for tomorrow. We continuously work to improve our performance — raising the bar individually and as an organization. We’re devoted to excellence in our work and committed to ensuring our teammates are given the mentorship, coaching, and resources they need to succeed.

We’re in service of our clients.

We’re hired by our clients to help them achieve their mission. Our primary concern is their success. It is the lens through which we make all decisions and assess good judgement.
