What we do
Sullivan Practice LLC is a boutique strategic advisory firm helping executive leadership teams build cohesion, clarity, and organizational health in an AI‑disrupted world. We work with CEOs and C‑suite leaders to eliminate dysfunction, fix misalignment, and create leadership systems that actually scale.
We are known for blending Patrick Lencioni’s organizational health frameworks with neuroscience‑backed leadership and executive coaching—delivering both insight and execution.
We've worked with 50+ organizations, including Comcast, Dell, Intel, HP, Adobe, Kaiser Permanente, Bayer, Netflix, HubSpot, Zendesk, Procore, and others. In each case, we guided the executive team through the same proven journey: from dysfunction to health, from chaos to clarity, to aligned execution.
