Hello! I’m thrilled to be teaching here at Cerebrum Tutoring Center. My name is Grace Paran and I’ll be teaching English courses. I have got a Master’s degree in Teaching English Language and I have had twenty years’ experience in international education.  As a teacher, I consistently endeavor to create a supportive and engaging classroom environment that promotes better learning. Together, let’s strive for excellence as we embark on this academic journey.

Over a career spanning more than 30 years, I have been a successful businessman and entrepreneur, a consultant in marketing, PR, and branding, a published author, and – above all – a teacher. I have been teaching for nearly 15 years in international settings to students from all over the world. In particular, I taught in universities in Suzhou, Nanjing, and Shanghai in China, in Paris, France, and in Lagos, Nigeria.

I bring a wealth of knowledge and good will into my classrooms and genuinely look forward to sharing what I have learned with students, helping them gain an advantage in the the world of work. And for fun too!
