After three decades advising CEOs and founders through their most consequential decisions, Marc has learned what most discover too late: the biggest obstacle often isn't the business. It's the life running alongside it, and the questions nobody around you is positioned to ask.
CEOs, founders, and senior executives who have built something real and are asking harder questions than their current circle can honestly answer. Some are burning out near the top. Some are questioning whether the climb is sustainable. Others suspect they've been on the wrong mountain all along. Marc's mentorship has centered on healthcare leaders, and it's open to leaders in other industries.
Marc works one-to-one with a small number of people at a time, by design. Engagements are unstructured, built around your situation rather than a fixed curriculum, with structured tools available when they help. You meet regularly, in person and virtually. If you're still in the early stages of building, this probably isn't the right moment.
In his thirties, at what looked like the height of a Wall Street career, Marc burned out. Honest guidance from a mentor brought him back. A mentor's job isn't to inspire you. It's to say what no one else in your life will say, challenge the assumptions you've stopped questioning, and name the patterns you can't see from inside them.
Your identity, the existence of the engagement, and anything you discuss stay confidential, with no exceptions other than those required by law. Marc doesn't keep notes beyond the engagement or reference clients publicly. He serves each client only as a mentor, never also as an investor or advisor. The client pays for the work directly, and Marc doesn't accept engagements from private equity firms to coach their CEOs.

Marc keeps his roster small so each person gets his full attention. If it's full when you reach out, you can join the waitlist and arrange an intro call in the meantime.
