In this episode of The Sharpen Podcast, host Steve Van Diest sits down with Mark Adelmann, a former CPA, CFA, church planter, and investment firm partner and CFO who is now an Acumen executive coach. Together, they look back at the small and large experiences that shaped him, from his early days as a baseball player and missionary to helping lead a firm through the 2008 crisis and a $13 million arbitration loss.

Mark shares what those seasons taught him about trust, the pull of “generally accepted” business practices, and why he now tries to do everything from a place of peace. He also talks about being stretched into private market investing after retirement, the value of stillness and journaling, and why the thing he missed most after leaving the firm was the team.

Practical Takeaways for CEOs and Leaders

  • Question what's "generally accepted" in your industry, and ask whether it's right, not just whether it's allowed
  • When you see a problem coming, rally your team around it before it forces a crisis
  • Before a big decision, check whether you have peace about it, not only whether the numbers work
  • Ask "What do I need to know today?" before writing checks, hiring, or firing
  • Do your homework, then hold the outcome loosely. Skill and trust work together
  • Lean into situations that stretch you, and ask what you're afraid of
  • Journal regularly so you can look back on what you've learned during hard seasons
  • Build a team that's a little ahead of you and a little behind you, and that will disagree with you
