Looking for 500 VERIFIED email leads - Cancer clinics

Cancer clinics - I want one lead per clinic, they need to be head of marketing (this is the best) or CEO or founder. Uk and Europe. They MUSt be private clinics, also NOT free clinics. private cancer treatment centres are good. so this is a good company to include for example -www.genesiscare.com- They are in several countries, so I would need head of marketing for all their countries or their overall head of marketing. Here is another private cancer clinic to use https://www.hcahealthcare.co.uk/facilities/london-bridge-hospital/specialties-and-treatments/london-bridge-hospital-cancer-care-services. Germany is also good for these for example this https://www.hallwang-clinic.com/. you can look for private cancer/oncology clinics/treatment centres
