MrTESOL.com successfully worked in the field of English as a Foreign Language for a number of years, beginning in 2004. During that time, we were involved in such things as coursebook creation in collaboration with major US book publishers, content creation, software design and platform management for a major digital provider of English language learning (for almost 400,000 registered users) and of course website design and digital marketing, which has become our main focus as of 2015.
