And just like that, BES Week 2026 became a core memory 💜✨

It’s truly a core memory for some of us to experience such a remarkable series of events, which not only invited us to have fun but also allowed us to learn valuable lessons that we will carry with us along the way.

We thank all of you who participated, supported, and became part of making PRISMATIC 2026: The Behavioral Science Week possible. This week-long celebration of joy, excitement, and meaningful connections became a reminder of how vibrant and passionate our BES community truly is. 🫂🤗

From the unforgettable moments to the lessons and memories we gained, PRISMATIC 2026 will always be a chapter worth looking back on. Thank you for making this celebration brighter, more colorful, and truly one for the books.

I FOUND MY WAY HOME, I FOUND MY WAY HOME. 🎓✨

For many of us, BES became more than just a program—it became our home. It is the place that saw every version of us, taught us meaningful life lessons, and shaped us to become better.

As we look back on our Baccalaureate Mass, we are reminded of how far we have come and of the people who walked this journey alongside us. Through the years, BES has been a community that nurtured us into who we are today.

To our beloved BES Batch 2026, as you take your next steps beyond the Arch of the Centuries, may you carry with you the memories, experiences, and values that made your stay in BES meaningful. And, no matter where life leads you, this community will always be a place you can come back to—a home that will always welcome.

Congratulations, BES Batch 2026! 💜✨
