When a doctor/health practioner stops learning, he/she can no longer be called a 'professional'.
Agreed..but a certificate is a little easier to read than their mind
I'm just giving this issue some thought since getting a sense of the case load of the typical clinician. I don't think most patients have even a base awareness of board certification. Some practicing physicians are well established but have cards that say "board eligible". With little else but the gut to go on, seems like any distinguishing criteria like this should be understood by patients.
