DMA is a 501c3 nonprofit, one of the first computer user groups formed in the nation.
Our mission is to promote interest and knowledge in all facets of computer technology.
We are a valuable resource for all things digital.

Out of concern for the health of our membership and meeting guests and also because of Ohio restrictions on restaurants, until further notice we have canceled many in-person DMA meetings. We don’t want to completely shut down at a time like this. The DMA Trustees have decided to replace our typical face-to-face meetings with the use of the on-line Zoom product. Keep checking this page and also DMA Meetup Events page for updates. If you have questions, comments, or suggestions, feel free to visit our Contact us page and let us know.
