Suffolk Sister Cities International's annual achievements include hosting several events and activities, including picnics at the Suffolk Visitor Center Pavilion for visiting delegations, a Venetian Carnevale fundraising event, an After-Hours Business Social to teach the community about sister cities, cultural exchanges with sister cities in Suffolk, England, and Oderzo, Italy, fundraising for Project Peanut Butter, and so much more. SSCI's success can be directly attributed to planning, strong committee work involving outstanding volunteers, collaboration with other local organizations, and financial support from sponsors and foundations.
