What's the Name of That Book??? discussion

Date range: 80's or 90's
Topic: Young man with interstellar teleportation capabilities on the run from an interstellar criminal organization.
I remember it being a trilogy, but I can't recall more than that.
Can anyone help me out here?

And I figured it out: The Journeys of McGill Feighan by Kevin O'Donnell.

Link for the first book.
