Hi. I have a product that I would like to sell to plastic surgeons. The problem is that I don't know how to actually go about selling to plastic surgeons. Could someone with experience selling to plastic surgeons give me some advice on how to sell to plastic surgeons. Some things that I need to know are:

Should I cold call by phone or in person?
Should I try to setup an appointment with the plastic surgeon or should I just walk in his office and try to meet with him without an appointment?

A sample call script would be helpful too. Any information in regards to selling to plastic surgeons would be helpful. Thanks for any replies
