TGA board member, Tina Peña, shares a travel journal from Celle, Germany, capturing moments of hospitality, celebration, and connection during the 25th anniversary of the Tulsa–Celle Sister City partnership.

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.

Students from Tulsa’s Sister City of Celle, Germany spent the week in Tulsa with Riverfield Country Day School host families, celebrating 25 years of friendship between the two cities. Earlier this year, Riverfield students visited Celle, exploring sites like Heidelberg Castle, the Kölner Dom, and the historic Ratsherrensaal in Celle City Hall.

From classrooms to council chambers, from firehouses to family homes, the Tulsa-Celle partnership has grown through moments of welcome and exchange. Guided by chair Sandy Dizdar and supported by a strong and active group of volunteers, this connection is a living bridge. It is built on shared history, sustained by friendship, and carried forward by curiosity and care.
