Before serving in the General Assembly, Senator Sean O'Brien was an assistant Trumbull County prosecutor, a position he held for over 12 years.
Senator O'Brien is the founder of the Trumbull County Community Foundation, which gave out over $50,000 to local charities in its first year, helping seniors, children and those in need.
An eager outdoorsman who enjoys hiking, hunting and fishing in his free time, O'Brien is the co-chair of both the Ohio Legislative Sportsmen's Caucus and the Ohio Legislative Trails Caucus.
