Martin Geraghty is an exceptionally prolific penciller in the pages of Doctor Who Magazine, active since 1994. He can also claim to be its most versatile artist, since he's drawn non-parodic stories featuring eight different incarnations of the Doctor and well over fifteen companions. Only Mike Collins rivals him for the crown of "most Doctors featured in proper, non-parodic stories" — but Collins has only drawn stories featuring the Seventh through the Eleventh Doctors.
