Bain Mastery Coaching is based in Warsaw, Poland. Brain Mastery Coaching serves clients across Europe, and across other continents whenever the time difference allows. The customers are of different nationalities. However, despite cultural differences, human problems, and the dilemmas they come with, they are similar. Most customers I work with are based in Switzerland, Sweden, Denmark, Norway, Finland, Germany, the UK, and Poland. A greater number of coaching processes are virtual via Zoom, Skype, or other dedicated video conference tools.
