About Karrikins Group
Karrikins Group is a Denver-based, global-serving consultancy that combines business acumen, executive experience, and social science with the disciplines of consulting, facilitation, and coaching to create alignment and accelerate growth for leaders and their teams.
We deliver solutions for senior leaders, boards, and teams who believe they can deliver better results if only their teams were better aligned. Our Alignment Journey™ solution is perfect for larger organizations with complex, global, or cross-functional alignment gaps who need to accelerate business results and drive transformative growth. Our Alignment Institute® was born from our desire to make the power of alignment more available to leaders and teams of all sizes and configurations, from individuals who want to lean into their own development to small to mid-sized teams and organizations who want the powerful results that come from getting aligned.
Our newest offering, Dynamic Strategy™, is designed to bring out the strengths needed for you to confidently and successfully lead your team as you set and execute your company’s strategy for the future.

The Karrikins Group Story
Karrikins Group was born from a passion for creating positive change in the world one nudge at a time.
Since its beginnings as ChangeLabs in 2001, through its migration to Karrikins Group in 2007, and ever since, we’ve been geeking out over the power of aligned action.
Our enduring mission is to make HOW matter for as many leaders and organizations as possible.
We are so grateful for the global companies that have taken this journey with us, including De Beers, Brookfield Residential, Xylem, and Cisco Systems.
In 2020, our founder, Peter Sheahan, turned over leadership of the company to us. Together we are committed to taking the journey forward and bringing the power of alignment to a new generation of leaders.

Meet Peter Sheahan
Founder, Author & Keynote Speaker
Peter Sheahan founded ChangeLabs in 2001 with the aim of accelerating transformation within communities and businesses around the world. Peter recognized that sustained change required transformation on the inside and that the behavior-change thinking we were using as ChangeLabs could be applied to leaders and their teams. Peter’s vision of bringing this to businesses set the tone for how we developed our consulting services practice that is now Karrikins Group. We have built on our deep roots in behavior-change to continue enabling transformative growth for our clients.
