You can scrap Logan Roy and Don Draper as “Professional” is not a word that should be used in connection with either.

harvey specter should have been disbarred many time. terrible leader.

Malory archer.

I only know the ones from Star Trek. Jean-Luc Picard I guess.

Edit: Jill Valentine should be on this list.
