The qualified physicians in Marksville with postgraduate training in internal medicine are defined as internists. They should not be confused with "interns", who are doctors in their first year of residency training. Although internists may act as primary care physicians, yet it should not be assumed that they are "family physicians" "family practitioners" or "general practitioners". Their training is not solely concentrated on adult-treatments and may include surgery, obstetrics, and pediatrics. There are a number of Internists in Marksville. But before consulting one of them, one must be certain of the choice by considering the professional career & reputation of the professional.
