Personally, I've sported a seasonal beard from Labour day to spring for the past 13 years and kept clean-shaven during the warmer months.
For the past 3 years I've taken to trimming it into a Hollywoodian, which is basically a beard without sideburns:

Looks striking with a shaved head, if I may say so.
I initially grew the beard to help me "age" a little, because I had such a baby face and looked much younger than I was (I was 30 yrs old and looked like a teenager...yeah, to only have that problem again...sigh...) and found that appearing older garnered me a little more respect from patients, families and other professionals with whom I didn't routinely work with. Honestly, everyone said the beard aged me by about 10 years and it really did work as far as changing how people interacted with me. Sad part is that now that I'm in my forties, I really don't need the beard to give me that 'sage' look; the crows feet and laugh lines work just fine, but the beard stays on for the winter!
