As a pharmaceutical representative, how to visit a doctor for the first time?

The first time you visit a doctor, it's best to go with a colleague from your company who knows the doctor, so as to give the doctor a safer feeling. The first visit is usually to introduce yourself and give the doctor a preliminary impression (but generally speaking, the doctor can't remember you for the first time). Before the visit, you should collect information and have a good understanding of the doctor you are visiting; secondly, you should dress formally and neatly, and speak and behave properly.
