The Spring Festival at University School transformed global learning into a hands‑on celebration, filled with lively performances, shared meals, and cultural discovery. TU students, educators, and community leaders joined in the festivities, highlighting Tulsa’s Sister City connections and inspiring younger students to see themselves as active participants in our global community.

TGA marked the holiday season with a heartfelt ornament exchange between Tulsa and its Sister City of Celle, Germany—an especially meaningful tradition as the two cities celebrate 25 years of partnership. Supported by civic leaders, community partners, and friends in both cities, the exchange highlighted the enduring spirit of international friendship and collaboration. This year’s effort reflects how small cultural gestures continue to strengthen a relationship that has grown for a quarter century.

Zelenograd, Russia is known as the “green city,” and its Sister City connection with Tulsa runs deep.
