Welcome to Byron Trott’s club

Dec 29, 2014

Here is a selected list of key players in Byron Trott's network who provide one another advice unique to the billionaire set. A few also advise Trott's firm, BDT. Trott's clientele includes wealthy families from around the world, though this list of long-standing members of the club is decidedly Midwestern, like Trott himself.
