Often I listen to coaches saying they need a mentor coach to comply with certification requirements…
What about turning the perspective and say: I need a coach to keep learning about my caching style, continue learning about my clients and how I can support them best, or work with a mentor to improve something you are finding difficult to master? and of course to fulfill the certification requirement.
Plan your road map before you start searching for a mentor, so you can ask them what you want rather than going through the motions
