As An Instructor...
...with a Doctor of Pharmacy degree, I carry wherever I legally can. I have had many students who are physicians. They tend to reflect specialites.
When I taught with LFI, most of our physician student were orthopedic surgeons (who tend to be jocks) and obstetricians (who often feel threatened if they have been identified as abortion providers).
ER physicians, some of whom I've had as students since I've been teaching on my own, tend toward one extreme or the other - enthusiast or prohibitionist. Family-practice docs also seem to polarize in similar fashion.
Pediatricians usually are prohibitionists but I recently had one tell me that he had taken the training to obtain an Arizona CWP.
Back in California, where I worked for the nation's largest HMO, I once met an internist I knew from work at an indoor range. When I exited the shooting area he was waiting for me, with a request that I not mention at work that I had seen him shooting. On the other hand, Timothy Wheeler, founder and director of Doctors for Responsible Gun Ownership is a head-and-neck surgeon with the same organization and holds a California CWP.
