Welcome to the City of Union website.  We are proud of our community and glad you are here for a visit.  We have included valuable information about our city and hope that if you have any questions, the answers are here.  Please check out the sitemap located at the bottom of this page which will help you find additional information.  There is also a “Contacts” page if you have any comments.  I have been a council member in Union for twenty-three years and I am excited to begin a new term as Mayor.  Union is a beautiful place to raise a family, start a business or retire.  We are proud of our council, staff, and the services that we offer.  Union is located in northwestern Montgomery County, Ohio.  I hope you visit our city and see why Union is wonderful place to “Live, Work, and Play.” - Michael O’Callaghan
