We are pleased to announce, however, that PROMIS and Portobello Behavioural Health have come together to become the new custodians of the Cardinal Clinic in Windsor, ensuring its continued legacy of care.
PROMIS Clinics has built an outstanding reputation over 35 years for delivering safe, compassionate, and world-class mental health services, supporting more than 12,000 patients across its facilities in Kent and London. Established in 2016, Portobello Behavioural Health has rapidly become Europe’s leading provider of bespoke mental health solutions. Specialising in case management and behavioural health coaching, they offer tailored therapy, coaching, and comprehensive case management services from their centres in Guildford, London, and Lisbon.
As family-run, multi-generational healthcare organisations, PROMIS and Portobello Behavioural Health share Cardinal Clinic’s values and have had the privilege of working alongside the clinic and the Morrish family for many years.
Moving forward into this next chapter, we’re deeply aware of the responsibility we carry in ensuring Cardinal Clinic’s continued success. Collaboration is key, and we look forward to engaging with our colleagues, partners, and the wider community to share ideas and expertise. Together, we can build on the clinic’s legacy and continue offering exceptional care to those who need it most.
We will keep you updated on key developments over the coming weeks, including reopening plans. In the meantime, if you have any questions, thoughts, or ideas, we would love to hear from you! Let’s work together to ensure Cardinal Clinic remains a place of hope, healing, and world-class care.
