We're proud to have joined Pelotonia as a Pinnacle Partner alongside Huntington National Bank, supporting a mission that unites communities around one goal: ending cancer.

Pelotonia has raised nearly $340 million for cancer research, with 100% of every dollar directed to research at Ohio State University Comprehensive Cancer Center-James Cancer Hospital & Solove Research Institute. This year, SEI employees rode, volunteered, and stood alongside thousands of participants committed to advancing research and driving hope forward.

Thank you to everyone who participated in Ride Weekend and to Pelotonia for continuing to inspire action and impact.

Great partnerships extend beyond the office.

Tonight, some of our colleagues joined our partners from IBM for a Philadelphia Phillies tailgate before the game and enjoyed the opportunity to meet Phillies legend Gary "Sarge" Matthews.

Strong relationships. Great conversations. A memorable summer evening in Philadelphia.

We are honored to be named a Top Veteran Employer by U.S. Veterans Magazine, recognizing our commitment to recruitment, retention, and advancement opportunities for military veterans.

Thank you to our veteran colleagues. Your experiences, service, and leadership make our workplace culture richer and stronger.

Work hard. Be a great teammate. Have fun along the way.

The Phillie Phanatic's playbook isn't complicated, but it's a good reminder that great outcomes—whether in sports, business, or life—come from teamwork, dedication, and showing up for one another. At SEI, we're fortunate to work alongside people who bring that mindset every day as we help clients turn challenges into opportunities.

Sometimes the most important business lesson comes from a giant green mascot.

Pride Month is a time to celebrate, reflect, and continue building a more inclusive future—and we’re proud to mark the occasion across SEI.

During SEI Pride Week, colleagues across our global campuses came together to connect, learn, and support the LGBTQ+ community. From campus celebrations and local Pride events to educational sessions and fundraising efforts, the week was filled with moments that reinforced the power of community.

A special thank you to our colleagues in the SEI Pride ERG for bringing these experiences to life and helping drive meaningful impact. 🌈

Our colleagues around the world recently came together for our Global Wellness Summit — a day focused on supporting the whole self: mind, body, and community.

The day began with a global keynote from Exos High Performance Coach Michelle Rogerson, who shared insights on the “Flow State” — that sweet spot where focus, energy and performance come together. From there, colleagues joined breakout sessions on mental health, mindfulness, nutrition, financial planning, and grief support, with practical takeaways and meaningful conversations throughout the day.

There was also plenty of time to get moving and connect through various activities hosted across our campuses, such as outdoor yoga, pickleball lessons, and a vendor fair featuring local wellness resources.

It was a great example of SEI’s commitment to building a culture that supports well-being, connection, and sustained high performance.
