What is head doctor?

As an AI language model, I do not have personal experiences or information about specific individuals.

However, a head doctor is typically a senior physician who oversees a team of doctors, nurses, and other healthcare professionals in a hospital or healthcare facility. They are responsible for ensuring the quality of patient care, managing the medical staff, developing policies and procedures, and maintaining compliance with regulatory guidelines. Head doctors may also diagnose and treat patients, conduct research, and participate in teaching and training programs for medical students and residents. Their areas of specialization may vary, from general practice to surgery, pediatrics, oncology, psychiatry, or other fields of medicine.
