Before working at Mariakani, I volunteered at a local community center, where I tutored students from diverse backgrounds. I helped them improve their academic performance and develop self-esteem and confidence. I used creative teaching methods, such as role-playing and group discussions, to make the learning experience more engaging and enjoyable.
In addition, I have conducted workshops and training sessions for educators and mental health professionals on various topics related to counseling and psychology. I have presented research papers at conferences and published articles in academic journals.
Overall, I am passionate about sharing my knowledge and helping others achieve their goals. I believe that tutoring is an excellent way to make a positive impact on people's lives, and I am committed to providing high-quality, personalized instruction to my students.
