[Coach Tips](https://info.teachstone.com/blog/topic/coach-tips) - [Announcements](https://info.teachstone.com/blog/topic/announcements) ![](https://info.teachstone.com/hs-fs/hubfs/orlando-ttt-training.jpg?width=519&height=300&name=orlando-ttt-training.jpg) Beyond training reliable CLASS observers, our Teachstone trainers play a vital role in delivering on the promise of CLASS. Across the country and around the world, they help organizations understand that if you improve how teachers connect with students, children learn and achieve more—now and for the rest of their lives. These trainers will be contributing regularly to the newly updated Affiliate Trainer Blog to share updates, tips, and resources to support our affiliate trainers. You’ll find everything from training tips to information about new CLASS-based research and professional development programs.  This week, we’d like to introduce you to Teachstone trainers Curry Ander, Lisa Criss, Mary-Margaret Gardiner, and Sarah Hadden. Come back next week to meet the rest of our Teachstone trainers!  **Curry Ander, Staff Trainer** ![curry-ander](https://info.teachstone.com/hs-fs/hubfs/Blog_Authors/Curry-Ander.jpg?width=190&name=Curry-Ander.jpg "curry-ander")Curry was born and raised primarily in Maine and still lives on the Maine coast in a cabin in the woods.
