Oh yes you'll be speaking Spanish in the first two minutes of class!

27 years as an English teacher/ trainer in Barcelona gave me plenty of variety; I've worked with politicians, research scientists, GPs, office dogsbodies, CEOs & executives, shop assistants, an 80-year-old stroke victim in recovery, university professors & students, mothers trying to learn enough to teach their toddlers....
This isn't about my methodology, it's about YOUR NEEDS and capacities, and a methodology that works for you. But you will be talking a lot.
