Yes I agree that he has a full semester+ of undergraduate/early graduate "course work" in his books... but the first chapter of his particle physics book has almost zero math -- it's just a great story.

His elementary particles book - I say having skimmed and the not bought it, so a I may be wrong - looks a good place to start by virtue of both containing a full introduction to the phenomenology behind particle physics and also an introduction (but only an introduction, compared to (say) Weinberg) the mathematics behind it.
