I wouldn't go so far as to call him my hero, but a man I admire is my new boss, VADM Richard Carmona, USPHS, the Surgeon General of the United States.
Among other things:
- decorated Special Forces medic (I think that was his MOS in Vietnam)
- trauma surgeon
- SWAT officer
Then I heard the voice of the Lord saying, "Whom shall I send? And who will go for us?" And I said, "Here am I. Send me!" -- Isaiah 6:8
