Having successfully used the Managed Change™ methodology on many transformations as well as building change management capabilities for organizations, I can attest to the significant success and tangible business benefits Managed Change™ delivers. I have used Managed Change ™ for many years. It's truly impressive how adaptable and effective their approach is, consistently yielding positive outcomes for a diverse range of organizations, from major corporations like Motorola, AbbVie, and Northwestern Mutual, to dynamic startups and even non-profits. LaMarsh is a proven partner for navigating change and achieving lasting results.

I had the privilege of working alongside Jeanenne LaMarsh, whose insights laid the foundation of my change management expertise and influenced the development of the Prosci methodology. To this day, I rely on the LaMarsh Managed Change™ approach to guide large-scale transformations—it remains a clear, human-centered framework for navigating complexity. I’m especially pleased to see my longtime friend Christine Kreuser now leading LaMarsh Global. The legacy is in great hands.
