Hello! My name is Amy and I am very excited to meet you! I am a native of the beautiful state of North Carolina. I have a Bachelor's of Arts degree in Psychology and Child Developmental Psychology, a TESOL Advanced license and a TESOL Foundational license. I have been teaching both in and out of the traditional classroom for 16 years. I love teaching ESL and it has been amazing watching my students going from non- English speaking to virtually fluent! ESL is certainly a passion! My students have become like family to me and I feel so privileged to be able to teach them ESL.
Outside of the classroom, I enjoy spending time with my husband, 4 kids and my 3 cats! We love to travel and I would love to visit China one day! I am looking forward to getting to know you!
