I was looking for something different to apply to my Language School. Things in ELT are rapidly changing and you have to grow or else you will disappear. I wasn’t sure though what exactly to do. It was then that I heard about this amazing course. I joined XBrain not having many expectations. I thought it would be similar to all the previous courses I had done for my Professional Development. I soon realised though that this was not the case. This course was so practical and experimental. I realised that we are the solution to all the problems. We have to believe in ourselves, to respect ourselves, to find new ways to develop and to see our vision. We are capable of everything only if we see it and believe it. We should stop complaining and putting the blame on others.

I started observing and embracing my feelings. All these thanks to Theodora and her unique programme. I am so grateful for making me see the world differently and for becoming a better version of myself. Now. I can help my students even more and adapt all these beautiful things we’ve learnt to my teaching. Lastly, I feel that this is just the beginning… Theodora has shown me the way to a new mindset..where there is no room for negative feelings and thoughts. Everything is positive and happens for a reason. Meeting you Theo did happen for a reason indeed. Thank you for everything and apart from all a big thanks for being given the opportunity to express my gratitude publicly. These kind of educators and people are very rare. You are one of a kind doing magical things and affecting everyone in a magical way!!!


I feel that it is my duty to help my students in
more ways than just doing and following the book….that teaching them that what they learn in Greek, they should be able to do in English!

I knew all you can do anything you want to if you set your mind to it and that stuff, but I didn’t have an actual way of getting them to see it, believe it and actually do it!

That’s where Theodora and XBrain came into the picture! She’s taught me a lot, of course I’m still a work in progress, but then again aren’t we all? I’ve enjoyed growing with my students as I have been using bits and parts of XBrain throughout the year,
and am confident that with practice and
more confidence I’ll get better at bringing
out the best in my students.

Afterall, you can’t expect them
to change the world if
they don’t know that they can!


Xbrain is not just another ready made lesson plan.
Xbrain changes your whole mindset! It helps you find
yourself, which are your goals and how you can achieve them.
It is a”life changer”, it transforms you into your better self.

Personally, it had a tremendous impact both on my way of thinking and on facing every day’s hardships. Imagine the amazing results it could have in a teenager’s life!

As for the coach, my dear unique Theodora is always there for you, supporting you and guiding you in every step you take.


Have you ever felt that, despite everything is in its place, still there is something that is missing? Have you ever wondered … ‘I have everything that I want, so why part of me is empty?’. Those were my concerns till my way brought me to the threshold of XBrain…little did I know what was going to happen! At first I thought it was the right time to do something profound for my students, but eventually, I was the one to bloom first. XBrain sessions were so enlightening and transformational at the same time that made me reborn, redefine myself, reconstruct my mindset…..and that affected everyone around me! I started working with a group of teenagers, which was only a wishful thinking back in the past, and the outcome was beyond my highest expectations. It is a perfect win-win situation, as both parties involved learn pivotal life lessons. Imagine the blueprint this can leave in the heart of a teenager! And what kind of thinking adults they can become! For all those reasons, and for many more that cannot be expressed in words, XBrain has been proved more than an investment….it’s a blessing! As for Theodora, her name tells exactly what she is….God’s present!
