Nicole Notaro, Upper Elementary Core Teacher
B.A., Child Development, Tufts University
M.Ed., Education and Child Development, Tufts University

More About Nicole Notaro

Nicole joined the Acera staff in 2014 after teaching at Atrium School for 7 years. She is a passionate, enthusiastic and creative teacher with a strong desire to help each learner grow to his or her fullest potential. Nicole works closely with students, faculty and families, and has taught independently and with co-teachers. She has experience creating meaningful, engaging, theme-based curriculum in all subject areas for 4th and 6th grades, and is experienced with differentiating instruction between students of varying abilities and learning styles in many different settings. Nicole believes that effective teachers must be knowledgeable in subject matter content and able to choose between a range of pedagogies. As such, Nicole has striven to acquire a strong foundation in both academic content and developmental approaches. Nicole believes that teaching is both a moral and ethical endeavor characterized by sound judgment and mindful choices made as part of conscious planning. As a teacher, she seeks to create meaningful relationships with her students and support them in becoming more knowledgeable, able, and thoughtful individuals. Nicole believes teaching is an art form that requires the swift coordination of subject content and knowledge of ones’ own students, a process she finds intellectually challenging and extremely rewarding. She responds to children’s thinking, inquiries, confusions, learning needs and world views by listening to children’s expressed ideas and observing learning behaviors. Nicole uses these observations to influence her instruction.

More About Michael Hirsch

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. During that time, he helped placed over 20 drugs into clinical trials and published several papers in the field of diabetes. Despite his success, Michael was feeling unfulfilled and realized that his favorite part of being a scientist was teaching others his research and sharing his passion of science. After receiving his masters degree and Massachusetts teaching certifications, Michael taught Biology and Chemistry in public high schools for 3 years where his zeal and excitement towards his content made him a favorite among students. His belief is that everyone can be a scientist and his goal in the classroom was simple: experiment and solve scientific problems. Michael was attracted to Acera’s vision of curiosity, inquiry based conceptual learning, and an opportunity to work with like-minded creative teachers. He loves the collaborative nature of the school, its ever-changing curriculum, and ability to provide a cutting edge, cool, safe, and unique place for many different types of student to learn and practice their skills. In addition to science, Michael is also an avid musician, playing and recording with 7 instruments and is a published pop culture media writer.

Debbie Seidell, Math Specialist & Coordinator
B.A. in Mathematics, Brown University
M.S. in Mathematics, University of Washington

More About Debbie Seidell

An experienced teacher, Debbie has spent 12 years in the classroom, teaching high school and middle school math at a number of independent schools, most recently at Horace Mann School in New York.

At Acera, Debbie teaches mathematics, and also leads the Debate Club each Wednesday in our STEAM Learning Lab. Debbie loves that teachers and students follow their passions at Acera, with the freedom to design curriculum around student needs. Debbie likes to approach math as she did in her childhood: as a game with a specific set of rules; as a puzzle that requires abstract thinking and asking lots of questions. She encourages her students to ask about the Why’s in math class, and then empowers them to find and make sense of the answers. She wants her students to feel a sense of excitement and ownership over the process of doing math.

When not dabbling in number games and puzzles, Debbie enjoys a good argument. A born debater, Debbie has participated in both policy and public forum debate–as a student, coach and instructor. Though math and debate may seem to be at opposite ends of the spectrum, Debbie notes that the discipline of thinking logically has served her quite well in the world of debate.

A New Yorker who loves learning languages, Debbie is proficient in Spanish but isn’t satisfied with just being bilingual. Clearly unafraid of a challenge, she continues to “dabble” in languages like German, Japanese, even Hebrew. Debbie’s love of languages goes hand-in-hand with her wanderlust–she enjoys traveling to new places, especially those where she can speak the language.

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 founded the Acera School in 2010 to serve accelerated children of all learning styles and needs. A passionate educator with a strong belief in public service, Courtney always knew she wanted to bring innovative teaching to the classroom. But how? It took some frustrating experiences as a young teacher, a successful career as a software industry leadership consultant, and her own accelerated son hitting the limitations of public schools for Courtney to realize: To get to the teaching environment she envisioned, she had to build a school from scratch. And with it, a strong, diverse community of teachers and parents devoted to innovative education.

Courtney’s vision for our school rests on three pillars: Acera is a progressive school that serves accelerated children, with a specific focus on innovation in STEM education and how scientific inquiry is driven by creativity and independent thinking. Under her leadership, Acera has grown in just five years from some 30 students to over 115; from a makeshift school in a rented church basement to a financially secure non-profit now in its own building in Winchester; and from a school no one knew to one whose 8th graders consistently place into the High Schools of their choice.

Courtney’s ability to create strong teaching-teams and an environment in which teachers can be entrepreneurs, mentoring students on their individualized learning paths, is crucial to the school’s success. So is her relentless entrepreneurial drive: On any given day, you will see Courtney work on a fundraising effort, sort out math group placements, check in with a student during recess, negotiate with contractors, huddle with a teacher over an exciting student project, or welcome the Winchester Fire Department.

The spirit of Courtney’s can-do attitude radiates through our school, allowing teachers to take ownership and be innovators in their classrooms, and allowing students to break out of the boundaries of grade-level and similar expectations. It’s how Acera gets to be not just a vibrant school that continues to grow and innovate, but a microcosm of what is possible in education.
