Episode Summary

In this episode, we sit down with Dr. Sarah Mitchell, VP of People & Culture at Meridian Group, to explore how group coaching is reshaping leadership development at scale. Sarah shares the inside story of how her team transitioned from traditional executive retreats to structured group coaching cohorts and the dramatic results they saw across the organization. Whether you're an HR leader looking to build a coaching culture, an executive coach exploring group formats, or a business leader curious about scalable people development, this conversation offers a practical roadmap for making group coaching work inside your organization. You'll walk away with actionable frameworks, honest lessons learned, and a fresh perspective on what it truly means to develop leaders at every level.

Key Takeaways

We begin by understanding the Key-Takeways
Group coaching creates peer accountability that 1-on-1 coaching can't replicate leading to faster behavior change.
Meridian Group saw a 34% increase in engagement scores within six months of launching internal coaching cohorts.
The key to scaling coaching culture is training internal leaders as facilitators, not just hiring external coaches.
Psychological safety is the #1 predictor of group coaching success and it must be intentionally designed.
ROI on group coaching compounds over time: the relationships formed become the organization's informal leadership network.
"The magic of group coaching isn't in the content — it's in the mirrors. Leaders finally see themselves through their peers' eyes."
Dr. Sarah Mitchell, Meridian Group

Welcome back to Coaching Cultures at Work. I'm thrilled to have Dr. Sarah Mitchell joining us
today. Sarah, thank you so much for being here.
Dr. Sarah Mitchell
Absolutely. It started about two years ago when we did an honest audit of our leadership development programs. We were spending a fortune on executive retreats — beautiful locations, great speakers — but the behavioral change just wasn't sticking. People would come back inspired for a week and then fall right back into old patterns.
