As a Business Management graduate from Moi University, I had the opportunity to work as a tutor for undergraduate students in the same field. This experience allowed me to apply the theoretical knowledge I had gained in a practical setting, while also honing my teaching and communication skills.

I also assisted with the preparation of course materials and collaborated with other tutors and professors to ensure consistency in teaching and assessment.
