Making a historic impact in our nation’s capital.


Where decisions shape the future.

D.C. isn’t just our workplace — we’re proud to call the District home. Our local model enables us to provide end-to-end delivery leadership, build strong partnerships, and drive digital transformation strategies of all shapes and sizes in the D.C. metropolitan area. With a deep understanding of the unique challenges and opportunities, we’re dedicated to delivering innovative solutions that meet the needs of our clients.

A model of excellence

"It’s amazing what happens when you hire the right people and empower them as business partners to pursue what they are passionate about - you get stellar client results, happy people, and an amazing workplace culture!"

Managing Director

Everybody has a stake.

It’s one thing to invite diversity. It’s another thing to embody it. At SEI, we encourage our teammates to be themselves and back that up by creating an environment where our differences make a difference for our clients. Diverse experiences and perspectives lead to better outcomes. That’s why we welcome identities that challenge each other, unlock honest collaboration, and better every interaction.

Community Impact

Living locally means we’re able to fully embrace and enjoy our city. From touring iconic Capitol Hill to exploring the charm of Georgetown, our team’s strength is matched only by our love for D.C. A fundamental part of SEI is supporting the communities in which we live, whether through volunteering at Homeward Trails Animal Rescue or Miriam’s Kitchen.
