like a geriatric psychiatrist? I'd be more impressed with a child psychiatrist than a geriatric psychiatrist *if* the child psychiatrist was a good child psychiatrist and was as good at general adult psychiatry as the geri psychiatrist.
If it's a geriatric internist, I'd be more impressed with them...depending on their knowledge base and skill set of course.
We have to keep in mind that psychiatry is psychiatry....whether we mainly work in forensics, addiction, geri, whatever....it's still just one specialty. It's not like the subspecialties of internal medicine for example which are much more distinct entities where intense structured fellowships(and not just work experience in many cases) is actually needed to practice in that area. except for child, one doesn't need one of the 1 year fellowships to start working in any of the other areas.....
