TEFL Certified International Tutor with over 10 years Teaching Experience. Hello and welcome! My name is Callista, and I am a TEFL-certified English tutor with over 10 years of teaching experience. I have helped kids, students, professionals, and job seekers from different countries improve their English and become more confident speakers. My classes are relaxed, practical and focused on real-life communication. Whether you want to improve your daily conversations, prepare for a job interview, travel abroad, study for an exam or communicate better at work, I will help you reach your goals step by step. I hold a Bachelor's degree from the University of Lagos and an Executive MBA from Quantic School of Business and Technology, USA. Beyond qualifications, I bring patience, encouragement and a genuine passion for helping people learn. I believe the best way to learn English is by using it, so my lessons include plenty of conversations, discussions and interactive activities. If you are looking for a friendly tutor who will help you learn with confidence and enjoy the process, I would love to meet you in class. Book a lesson with me and let's get started!
