It all starts with a conversation.  Get in touch with as much information as possible about what you're after.  Based on that, Sumantha or a member of her team will get in touch with available options.

I've been an educator since 2006.  Having taught in various settings, I can wholeheartedly say that online teaching is excellent - in fact, it is better than face to face learning in many ways.  

Of course, some students may have specific needs which makes face to face lessons the only viable option.  But for most, online tuition is more engaging than face to face; students (and parents/guardians) are more relaxed, there are fewer distractions and online tools enable better interaction.
