John Windsor-Cunningham coaches actors privately in New York and on Skype. He hates taking money from actors. That's why he only charges $35 for private coaching.
London's National Theater education department remarked that John's coaching is "second to none in the world". He's worked with every major theater company in the UK and several in the USA, where he now resides.
He also teaches people all around the world how to have a good British or American accent -- even people who are not actors. People from Mexico, Australia, China and Turkey have worked with John on their accent.
