Ms. Antina Avery

I am excited to be a part of the Greenwave family. I am a graduate of Livingstone College where I earned my bachelor’s in accounting and Strayer University with a master’s in finance. After spending several years in the business sector, I took a huge leap into education. I started my educational career in Charlotte Mecklenburg Schools, teaching mathematics. My educational career expands to charter, private, and public schools, including alternative. After several years, I transitioned to Career and Technical Education and taught business classes (Career Management, Personal Finance, and Accounting). The last two years have been focused on obtaining my second masters in School Administration, which brings me to my current position and home. When I am not working, I enjoy spending time with my family, cooking, watching Hallmark, or reading. I am eager to get to know each of you and look forward to the impact we will make on our students' lives.
