Orthopedic surgeon, Founder XpertHealth
The future success of all of these innovations lie in a stronger restructured foundation of the entire medical system. An endeavor not to be made by one company, but by partnering with many care providers around the world.
In my own practice, I see many different people and cultures. It is a place where real human contact makes the difference in spotting problems early on and connecting with people as a partner in health. We should never forget that access to care & medicine is a basic human right characterised by the impact of feeling sick, working to get healthy and the personal contact of those who CARE… all HUMAN.
