What it is
Introspection is the last road most CEOs willingly travel.
A Trusted Advisory Group™ connects you with impartial peers beyond your usual network — giving you access to new avenues for growth that your current echo chamber cannot provide.
Each group is limited to eight to twelve leaders, curated for diversity of industry and geography. Sessions are monthly, professionally facilitated by Matthew Cahill, and governed by strict confidentiality.
What's said in the room stays in the room. That's what makes the honesty possible.
How it works
Structured candor. Curated peers. No agenda but yours.
Each session opens with a check-in on the most pressing issue each member is navigating. Members then present a challenge — a decision, a conflict, a strategic uncertainty — and receive structured honest feedback from the group.
Matthew chairs every session as a thinking partner with the expertise to push back, reframe, and surface what the group is circling around but not saying directly.
Members consistently report that TAG™ peer relationships are among the most valuable professional relationships they have — precisely because they exist outside normal organizational pressures.
