A new county treasurer has been sworn into office. As of Sept. 1, Ken O’Brien, a former Delaware County commissioner and Berlin Township trustee, is the newest elected official in Delaware County. He oversees an operation that is charged with managing the collection and investment of the county’s monies.
O’Brien said he is ready to focus his team on the core mission he has set for it.
“I am identifying ways that we can serve the public quickly and more efficiently,” O’Brien said. “We will make sound investment decisions that are safe, secure and transparent in their provenance, and I look forward to strengthening the relationships we have with other elected officials and staff so that we will work better together to serve the people of Delaware County.”
O’Brien brings experience as a former stockbroker and as a seasoned public servant. Among the elected positions he has held are Delaware County Commissioner (2009-2015); as a clerk/fiscal officer in Berlin Township; and, most recently, as a trustee in Berlin Township. O’Brien won office as County Treasurer in the November 2024 general election, but, due to the mandates of state law, his term did not start until the first Monday of September 2025 and will run through Sept 2, 2029.
O’Brien hails from a family that has lived in Delaware County since 1827. He began his professional career in education, teaching for more than 24 years and becoming National Board Certified. He has served as Vice-President of the Central Ohio Youth Center, responsible for policy and budgeting at the four-county youth detention center.
