The economic, community, and downtown development activities of SIEDC would not be possible without the strong support of the private- and public-sector partners. Please contact President & CEO Aaron D. Montz if interested in learning more about becoming a member, and he would be happy to speak with you.

Grow the Economy, Strengthen the Community

Through their financial contributions, all TSEP members give us the resources we need to do our award-winning economic, community, downtown, workforce, entrepreneurship, and rural development work – work that has placed Tiffin and Seneca County among the top ten nationally (out of almost 600) rural micropolitans for economic development and top three downtown Main Street communities in Ohio for new businesses, jobs, and investment.

In the last 8 years, we’ve seen more than $500 billion in new investment and 2,000 new jobs. The population decline has stopped, poverty has been cut by a third, and unemployment is now consistently a point below the state and national average. Read our most recent annual report.
