Currently our office is not doing Apostilles as we are working remotely. I would suggest to contact the state office of authentications for Ohio directly and see how they may be able to help. Their website is https://www.ohiosos.gov/records/apostilles-certifications/
An Apostille is neither required nor necessary. The CeDiploma® has legal standing, is non-repudiating, and can be validated through the University's website to provide absolute confidence in the credential's authenticity. All questions should go to firstname.lastname@example.org or 740.593.4196.
