About Tri-State Development

Tri-State Development at Culver-Stockton College supports the region by cultivating collaborative relationships, promoting interdisciplinary problem-solving, fostering the expansion of academic-organization-industry initiatives, and developing an environment for collective impact to address the current and emerging political, economic, and social challenges in the region.


TSD was formed as a collaboration to get things done! Recognizing then and now that we accomplish more when we work together. We work hard to connect ideas and the people who have them to each other so that our goals resonate more effectively.


We help ensure that ideas make an impact! By supporting projects and programs that contribute to our local communities and regional goals, we help drive outcomes!


TSD is a collection of big thinkers, energetic doers, and motivated partners who help move ideas, create jobs, and propel the regional economy forward.


The mission of the Tri-State Development is to bring together stakeholders to identify challenges and opportunities within the 3 state regions of Northeast Missouri, Southeast Iowa, and Western Illinois and to work collaboratively toward regional outcomes that will encourage investment in our communities and enhance the lives of our citizens.


We envision a sustainable, replicable model for collaborative impact among academic, industry, and organizational partnerships through strategic discussions, and projects, leading to program outcomes.
