A pediatrician diagnoses and treats injuries, diseases, and infections in young people. They perform physical exams, recommend treatment programs, and use their medical knowledge and experience to diagnose patients. Pediatricians need a doctor of medicine degree which requires 3 years of undergraduate education and 4 years of medical school. Starting salaries for pediatricians are around $125,000 per year, though residents earn less. With experience, pediatrician salaries can increase to over $175,000 or $300,000 per year. The job outlook for pediatricians is strong as they provide essential healthcare to children who would otherwise lack medical treatment and records of illness.
