Longmont Sister Cities Association

In 1956, President Dwight D. Eisenhower proposed the people-to-people concept that lead to the development of Sister Cities International. It was Eisenhower’s belief that strong relationships established between cities in the United States and cities of the world would lessen the potential for world conflicts.

Based on this concept, in 1991 local businesses and city government joined together to establish Longmont’s first Sister City Association with Chino, Japan. In 1995 the Longmont Sister City Association (LSCA) was founded to manage the sister city relationship and to relieve city employees of the many tasks and responsibilities associated with coordinating sister city activities. Shortly thereafter LSCA became a member of the Sister Cities International (SCI) organization.

In 1998 Ciudad Guzman, Mexico became Longmont’s second sister city. The connection between Longmont and Ciudad Guzman is based on similarities of the two cities and Longmont’s large Hispanic population.

And, in 2020, we became the first (and only) city to partner with a First Nations Community, the Wind River Reservation in Wyoming!
