Our story

We started Treeline because we saw too many transformations fail — not for lack of strategy, but for lack of care.

After years leading transformation inside some of the world’s most complex organizations, Matt and Chase kept seeing the same problem: brilliant strategies that fell apart in execution because nobody had paid attention to the humans who had to live them out — or the structures that made those strategies impossible to actually run.

Most consulting engagements are either structural or human. Operating model work on one side. Change management on the other. Treeline was built on a different premise: that you can’t redesign how an organization works without addressing how its people think and behave — and you can’t change culture without changing the structures that create the conditions for that culture.

What makes the Treeline partnership distinctive isn’t just the range of experience. It’s the honest belief that transformation is first and foremost a human endeavor — and that the organizations that come out stronger are the ones that treated their people that way throughout.

Across 150+ engagements in 13 countries, we’ve worked at every stage of transformation — designing operating models from scratch, rescuing stalled programs, building cultures that outlast any individual leader. Every engagement is led by us, not delegated to a team we’re managing from a distance.
