The Guernsey Chest and Heart Association, established in 1971, is a self-funded registered charity dedicated to improving the health of the Bailiwick community through essential health screening services. Founded by the late Dr. Sam Gregory, the organization inaugurated its Medical Centre in 1974, strategically located on the grounds of Princess Elizabeth Hospital. The Association operates independently, despite common misconceptions of being under the state's jurisdiction.

Guernsey Chest and Heart provides vital programs that focus on screening for respiratory and circulatory diseases, addressing significant health concerns such as coronary heart disease. With annual operating costs exceeding £100,000, the Association relies solely on the generous contributions from individuals, corporate sponsors, and community organizations to sustain its services. By offering comprehensive health checks, including blood pressure monitoring, the organization plays a critical role in enhancing public health and awareness. Community support is essential for the continuation and expansion of these services, making every donation impactful in the fight against illness in the region.
