1. 1st degree misdemeanor DV convictions cannot be sealed; lesser-degree convictions, such as 4th degree misdemeanor DV, or 2nd degree misdemeanor Attempted DV, can be sealed.
2. You could apply for a pardon from the Governor. These are very difficult to get.
3. You could try applying somewhere where they're desperate for nurses. The military? Out in the Bakken Formation of North Dakota? You're going to have more trouble finding a job than if you didn't have this, but I'll bet that you can find someone, somewhere, to give you a chance.
I agree with Mr. Holcomb, but I would add you to could try to withdraw your plea in the case and see if prosecutor would amend to something that is "expungeable"(the offenses listed above or a disorderly conduct) Then it would be expungeable. It would be difficult to do, but is possible, and may be worth your effort given your situation. I would talk to an attorney in the Dayton area.
