our experience at a glance

Sullivan Practice is a boutique advisory firm focused on the factor that most often determines whether teams succeed or struggle: organizational health.

  • Cohesion. Clarity. Cadence.

  • Patrick Lencioni's frameworks

  • Cohesion: politics → trust

  • Clarity: confusion → direction

  • Cadence: death by meeting → decisions

Unlike traditional consulting that ends with a workshop or off-site, we partner with leadership teams through the full organizational health cycle. Real transformation requires consistent work, reinforcement, and accountability over time.

clients call us when:

  • Infighting between two senior leaders has impacted quarterly results, and now their teams won't work together either.

  • Your leadership team has turned over 20% in six months, and the people who are left are waiting to see who goes next.

  • Your AI initiative spans several divisions, yet there's no ROI over the last two quarters.

  • Your best technical leader is losing his people, and you need him to become a people leader before you lose another one.

  • You have re-orged twice in the last eighteen months, and nothing's working.
