Stalis Appoints John Flannery as Chief Operations Officer to Scale Delivery in the United Kingdom and Ireland
London, United Kingdom and Dublin, Ireland – Feb 19 2026
Stalis, a leading provider of clinically safe data services for healthcare organisations, today announced the appointment of John Flannery as Chief Operating Officer (COO). John joins Stalis to support the company’s ambitious growth plans across the UK and Ireland and to further strengthen service delivery to customers.
John brings over 20 years of leadership experience from healthcare technology and professional services organisations in the United States. John’s background spans the business lifecycle with strengths in process improvement, developing strong employee culture, and growing sustainable enterprise value.
Based in Ireland, John will lead international operations, supporting the expansion of Stalis Ireland while providing strategic leadership for the broader Group.
Ireland’s health system is at an inflection point. As the National EHR programme accelerates, success depends on a single, clinically safe national foundation for historical patient data. With over 40 years of specialist experience in complex healthcare data migration and archiving, including deep HSE experience, Stalis is uniquely positioned to address this challenge.
Kieran Hughes, Chief Executive Officer at Stalis said:
“John’s proven track record in high-growth environments makes him an excellent addition to the Stalis leadership team. His appointment reflects our continued investment into Ireland and the United Kingdom as we support healthcare organisations through critical digital transformation programmes.”
John Flannery said:
“I’m excited to join Stalis at this pivotal moment. The organisation has built a strong reputation for clinical safety, delivery outcomes and trusted partnerships. I’m looking forward to leading the expansion of Stalis Ireland while scaling the Group’s operational capabilities.”
