I have to say it has been interesting reading everyone's replies to
this question. Here is mine. There needs to be distinction between
my personal, professional and other aspects of my life. My kids call
me Dad. My friends call me Tom, Tomdizzle, Big Tom, etc. At church
they call me Bro Jemison. My wife calls me... on second thought never
mind. When I graduate my patients will call me Dr Tom, Dr J, Dr
Jemison, Doc, etc. I know for me it will be important to have that
distinction in my life. In our profession, when there are
so many impostors in unlicensed states especially, being called Dr So
and So is very important. Being called Doctor demands a little
respect and expectation. I don't call my professors at school by
their personal names, I use their professional names. I just know for
me, when patients call me Dr (after I graduate of course) whether they
know it or not, they at least acknowledge my efforts to get through
all this schooling.
Also, while I am at it, clients take advice and guidance. Patients
receive medicine and medical procedures.
