Phoenix and Hermosillo, Sonora, Mexico, celebrated a major diplomatic milestone on October 16 when city leaders formally reaffirmed their 50-year sister city partnership. The ceremony took place at the annual Mayor's International Gala, an event held at Chateau Luxe that drew a crowd of more than 480 guests.
The core of the evening was a joint signing document executed by the mayors of both cities. This action served as a public commitment to continue the cooperation and friendship that has defined the relationship since its inception in 1976. The two communities have maintained this link for five decades, using it as a foundation for cultural and economic exchange.
Mayor Kate Gallego addressed the attendees, describing the event as a showcase of the ambition that defines Phoenix as a global city. She credited the support of community partners for creating opportunities for international collaboration. Gallego stated that the partnership strengthens the city through meaningful cultural exchange.
The gala also served as a platform for recognizing local leaders who contribute to global engagement. Mayor Gallego presented the Global Leadership Award to Mayo Clinic. The organization also honored Dr. John Shufeldt with the Global Citizen Award and the Flinn Foundation with the Global Philanthropy Award. These awards were given to individuals and groups whose work expands Phoenix's international presence.
Gary Jackson and Oscar De las Salas served as co-chairs for the event for the second consecutive year. The evening’s theme was inspired by orange blossoms, and the menu reflected the culinary traditions of the Sonoran region. Live entertainment accompanied the meal, highlighting the cultural similarities between the two border cities.
Phoenix Sister Cities, the nonprofit that organized the event, was founded in 1972 to promote peace and understanding through citizen diplomacy. The organization is supported by more than 30 sponsors and donors who help fund its mission. Proceeds from the gala specifically support the Youth Ambassador Exchange Program, which allows young people to develop leadership skills and build international connections.
The relationship between Phoenix and Hermosillo is one of the longest-standing in the organization's portfolio. The 50th anniversary marks a historic point in the history of cross-border cooperation in the Southwest. The formal signing ensures that the institutional framework for future projects remains in place for the next generation of leaders.
