Mr. Serrano

Teacher at Medellín Boys' School, loves environmental science

  • 🇨🇴 Medellín, Antioquia, Colombia
  • Medellín Boys' School
  • Since 2004
  • Spanish
I came to teaching late, after working as a radio technician, and 22 years later I still can't imagine doing anything else. Outside the classroom I sing in a choir. Inside it, I stay late on Thursdays for anyone who needs it.
