Choosing a coach is an important and personal decision. I recommend reading the following two resources:

• How to Find (and Choose) a Coach by Ed Batista is a great guide to your decision-making process. It will also give you some good ideas for questions to ask me in our first call.
• Homebrew Ventures’ Guide to Executive Coaching by Beth Scheer is full of great tips on how to find and work with a great coach.

If you’re looking for coaches:

• Andy Dunn, former Co-founder & CEO of Bonobos, crowdsourced a list of coaches you can find here: The Best Executive Coaches on the Planet, According to You.
• Ed Batista also maintains a running list of coaches he recommends on Twitter here.
