Graham Stubbs
Chief Executive Officer

Graham is CEO and one of the co-founders of Diona. The idea for Diona and new systems of engagement solutions was born out of personal experience, engaging with government organizations as a result of his son Owen’s special needs and severe physical and intellectual challenges. His business passion is helping governments help people and trying to make a difference. Prior to Diona, Graham spent many years in the Health and Human Services technology market with Cúram Software, and in his formative career years in the 1990’s worked for many leading technology companies in the Bay Area including Oracle and EDS.

When not working, Graham loves playing bad golf with his wife Sheelagh (who is the real golfer in the family), hiking, open water swimming, traveling, spending time with family and watching rugby. Graham is a graduate of Trinity College Dublin.
