Misty Lehman


Misty is originally from Cincinnati, Ohio, but she currently resides in South Wales, UK. She has been teaching English since 2013. She taught in a Japanese eikaiwa (English conversation school) for 22 months and then began teaching online in 2017. She has experience teaching children as young as 2 and adults as old as 80. She holds a BA in English with a criminal justice minor, as well as a TEFL/TESL/TESOL certificate.

Misty loves traveling, interacting with new people, and learning about different cultures. She finds that while she is teaching you English, she learns so much about your country, your native language, and your culture. Teaching English is like traveling to a different part of the world every day and meeting a new friend. Each student is unique in their own way, so while Misty’s teaching style might be quick-paced, target-focused, and structured with one student, it might be relaxed, informal, and relational with another. She approaches each student with kindness, compassion, and patience no matter what. Her goal for you is to have fun and be confident with the English language.

In her free time, Misty enjoys running, hiking, and anything outdoors. Between lessons, she often goes for a jog along the beautiful trails just outside her home in the Welsh countryside. She also has a passion for cooking and experimenting with new recipes in her kitchen. If you have a conversation with her about local cuisine in your country, it is highly likely that she will try to cook it in the future!
