Unclaimed listing: created from charter-published data

Facebook Reddit Pinterest Email

I teach Russian language. I teach small group classes and work with students one-on-one, in person, in Chicago and the surrounding suburbs and online, from beginning to advanced levels. I work with children, teenagers, and adults. As a native Russian speaker, I use a grammar-based approach to Russian with an emphasis on correct pronunciation from the very start. I prepare interested students and accompany them to the Illinois-Indiana Olympiada of Spoken Russian. My online students have come from as far away as California to join! I have helped students prepare and apply for opportunities to study abroad.

Subject: A quick favor: one minute Hi everyone, We've been listed on Vendvera, a free directory of vendors that California homeschool charter schools approve. Families use it to find providers their charter has already approved. Our page is live, but it doesn't show any families yet, and that number is the first thing most families look at. If you come to us, would you confirm it? And if you have a minute more, tell other families why your kids love coming here. https://homeschool-vendor.vercel.app/vendors/2006 You'll sign in with your email so it only counts real families. The review is optional. It's offered right after you confirm. There's nothing to buy and nothing else to do. Thank you. It genuinely helps other homeschool families find us.
