A calm environment
dedicated to your care.
Situated within a private estate in the heart of Windsor's green belt, Cardinal Clinic offers a therapeutic environment that is a world away from the clinical anonymity of a hospital ward.
Our grounds and facilities — from the chef-prepared meals to the comfortable, light-filled rooms — are designed to support the healing process. We believe that where you receive care matters as much as how you receive it.
