The Catalystic Leadership Team

Catalystic Leadership was founded and led for many years by Dan Coombes. Over time, Dan’s long friendship with Kevin Krosley grew into a professional collaboration when the business needed an additional executive coach. Today, Kevin leads most client engagements, while Dan continues to serve as Founder and Executive Coach Emeritus—advising and coaching Kevin while making more room for family, fishing, and the travel connected to both.

Dan Coombes

In my career, I've navigated a wide array of leadership roles, spanning Sales, Marketing, Operations, and HR, eventually leading global Leadership Development and Executive Coaching initiatives for over 22,000 employees at Monsanto. I've had the privilege of working with senior leaders in many public, private, and non-profit organizations around the globe and across multiple industries, mainly in agriculture, sporting goods, financial services, healthcare, and retail. My passion as a coach and consultant lies in helping leaders at all levels—whether in the C-suite or just starting out—to achieve their full potential and create lasting impact within their organizations. While my coaching covers a broad range of topics, my consulting work focuses primarily on building leadership effectiveness, enhancing team and organizational performance, and guiding organizations through major transformations.
