Michael began his work life as a scientist in the exciting world of Kendall Square biotech researching and creative therapeutics for metabolic disease and inflammation.

His belief is that everyone can be a scientist and his goal in the classroom was simple: experiment and solve scientific problems.

Courtney Dickinson, Founder & Director
B.A., Dartmouth College
Certified Teacher
Leadership & Company Culture Consultant/Culture Architect, Sapient Corporation

More About Courtney Dickinson

Connect with Courtney on LinkedIn

Courtney Dickinson is a passionate educator with a strong belief in public service and innovation in education. Initially, Courtney was certified as a teacher and planned to work in public education. Things did not unfold that way, however, and she spent the first 15 years of her career in industry – both as culture architect at Sapient Corporation and then as a management consultant for other high growth organizations.  

After her own children started in public schools, Courtney saw that there was a disconnect between what kids needed in school and what they were getting, and in the 20 years away from education, things in the public space had become worse, not better. Realizing that a return to education was essential, she became an advocate for change.

The decision to found a bootstrap start up school was a difficult one. Courtney dove in, galvanizing prospective parents and teachers around a shared mission for what school could be. A year later, Acera opened in Melrose with an inaugural class of 37 students. 

“Building the engine while you fly the plane” has not been easy, but with persistence and emphasis on continual improvement, the concept came alive: early and deep exposure to STEM, individual learning plans for every child, an eclectic blend of pedagogy that empowers teachers to create environments of discovery, authentic engagement, learning, and growth in their classrooms, and partnerships with scientific thought leaders in Greater Boston to link learning to real innovations and the challenges of our time. 

From the very beginning, Courtney’s intent was to create a model that could happen anywhere. After years of developing and pilot-testing innovative curricula at Acera School, Courtney and her team launched AceraEI – an outreach division that brings Acera’s Tools to Transform Schools into public education. Through professional development workshops, ongoing support, and metrics for success, AceraEI partners with public schools to implement these Tools in a way that fits each school’s unique setting and needs, empowering educators to be change agents and leaders in their schools and school districts.
