The new Cleveland Clinic building in London is growing from within - see for yourself - it's just across from the Buckingham Palace:
Cleveland Clinic London is on track to open a new 200-bed private healthcare facility near Buckingham Palace in January 2021. The opening will coincide with the system's centennial.
Cleveland Clinic London will focus on 4 specialties: cardiology, orthopedics, digestive disease and neurology. And it will open 3 outpatient facilities. The Clinic will employ about 50 doctors and a staff of about 200.
