Our Team

Georgette Dobkin
 Director, Learning Architect, Guide
     Georgette always knew her calling was to work with children.  With a Master of Science in Teaching degree from Fordham University, Georgette taught for two decades in public and private schools in New York, Maryland, Florida and Georgia. During her tenure in traditional education, she taught and served in leadership roles at a Cobb County elementary school, co-founded two foundations at her children's schools, and was the head of the ESOL program for a Fulton County elementary school.  
     In 2017, Georgette left traditional education to create a space where learners could pursue their greatest potential with choice, independence, and joy. She first co-founded the Homegrown Learning Academy, cultivating a multi-age learning program there, before discovering the Acton Academy network. In 2019, she launched Acton Academy Marietta, excited to join the community of affiliates reimagining learning and empowering young heroes across the US and around the globe.
     Georgette serves as part of Acton Marietta’s learning design and administrative team and will guide our elementary-aged studio during the 2022-23 year. She feels honored to be a part of the learners’ Hero’s Journey!

Brooksie Pollack
Guide
After earning her BA degree in Early Childhood Development and a multi-subject teaching credential from San Jose State University, Brooksie taught kindergarten and 2nd grade until she and her husband moved to Georgia. She continued her teaching career working with 1st through 5th graders in the Learning Lab at Paces Academy in Atlanta. As her family began to grow, Brooksie left teaching to focus on motherhood and became active in her children’s interests including scouting and coaching Odyssey of the Mind. As an Odyssey coach she led her children’s teams to World Finals 3 times as well as earned the Ranatra Fusca Award and a spot in the Coaches Hall Of Fame.

In the spring of 2020 she began homeschooling her high schooler, and later her 5th grader. Now that her two oldest children are off to college and her youngest has landed as an Acton Eagle, Brooksie is excited to take on her newest role as the Explorer studio guide and encourage the youngest eagles to find their passion, discover a love of learning, and watch them grow into the heroes they truly are.

Amanda Schrembeck
Part-Time Guide
Amanda discovered Acton Academy Marietta after realizing she wanted a learning environment that would not stifle her boys' individual uniqueness, but, rather, would nurture it and let them explore who they want to be. While watching her son go to school, she realized our educational system could be reimagined and she wanted to be a part of that. She is excited about working with a team who is passionate about what they do and about bettering the lives of children. Amanda is Montessori certified and works with Acton's youngest learners to create a strong foundation for life-long learning. She enjoys reading, traveling, and eating lots of good food!
