Dr. Rob speaks out:

I work as many, if not more hours as a specialist. I trained for four years in residency, where many of them trained nearly the same length of time. My knowledge base is far broader, and my direct effect on the lives of people is greater. It is part of a normal day that primary care physicians save the lives of their patients. We diagnose them with heart problems before they become serious, we diagnose appendicitis (or gallbladder problems, for that matter), and quickly decide regarding the seriousness of people’s illnesses, referring to the cardiologist, gastroenterologist, or surgeon who does the final procedure to “save the patient.”
