BALTIMORE, July 09, 2021 (GLOBE NEWSWIRE) -- Cadmium, a leading events and learning platform, today announced that it has acquired EventRebels, a Baltimore, Maryland-based events and registration software company primarily serving the conference and trade show markets. The acquisition underscores Cadmium’s commitment to building a unique, market-leading software platform offering continuing education, professional development, events, learning and content management solutions to associations, non- profits, healthcare & life sciences organizations.

“ISSTD is thrilled to hear about the acquisition of Event Rebels by Cadmium,” says Mary Pat Hanlin, MPS, DES, Chief Executive Officer, International Society for the Study of Trauma and Dissociation. “As a long time user of both products, we are excited to see how the addition of an event registration system will complement and integrate with the products already in the Cadmium portfolio. This acquisition will provide our association with a one-stop shop for all of our event and education technology needs with the high-quality service that we love from both companies.”
