A professional coach usually needs mentor coaching for two reasons: either as part of international certification or for professional development. Every coach who values their skills and constantly develops their skills has their own mentor coach.
When connected to the certification process, mentor coaching generally focuses on the core competences and ethical rules defined by the ICF (International Coaching Federation). I offer mentor coaching for ACC and PCC level certifications together with Kay Wolff Coaching. Here you can find more information about us. Kay and I are both mentor coaches certified by the ICF. You can read more about Kay on her LinkedIn profile and Kay Wolff Coaching LinkedIn company page.
