You are going to have problems sealing your criminal record. First, in Ohio, domestic violence under O.R.C. 2919.25 cannot be sealed. Second, unless an exception applies, only those who are first-time offenders are eligible to get their record sealed (applies to misdemeanors and felonies).
I'd advise you to contact a Marysville criminal defense attorney for a consultation. After reviewing your record and looking for an exceptions in Ohio law, they could conclusively advise you whether or not it would be possible to seal your record.
