Arthrex is one of the leading Orthopaedic manufacturers in the United States. How do you become an Arthrex rep? Since Arthrex is a manufacturer, you wouldn’t be a sales representative for them directly. In order to become a sales representative for Arthrex you have to be hired by a distributorship. You can call Arthrex and find out who the local distributorship is in your area and apply with them. Medical Sales positons are very difficult to get and using a recruiter is highly recommended.
