Kate Dao

Parent & Founder

Kate is a lifelong learner. She believes children should have the freedom to explore their natural curiosity and creativity. When this happens, children are happy. They are self-motivated because learning becomes a joy. Kate founded Acton Academy East Bay to create a space for students to experience an education that encourages critical thinking, imagination, creativity, and exploration. Her mission is to allow all students to test their ideas to discover how and why things work and to find answers to their questions in a caring and nurturing environment.

For the past decade, Kate has worked as an educator developing individualized programs for K-12 students that emphasize critical thinking and problem-solving. Her work has helped countless students succeed academically and realize their full potential. Before her career in education, Kate worked at startups in the tech industry-leading teams in marketing, HR, and business development. She received her bachelor's degree from the University of California at Davis and a master's degree from the California State University of Sacramento.

Han Le


Han has a strong belief that learning is not only about reaching the destinations, it is more about the growth that students experience on the journey. She understands that learning is not always a linear process, students are likely to encounter many failures and setbacks along the way, yet as long as they choose to move forward, the successes that they achieve could be great and unimaginable. She also advocates students prioritizing their mental and physical health on their academic journeys because their well-being will be the most valuable asset in any quests they choose to participate in. Han received her Bachelor's Degree in Comparative English and Literature at San Jose State University and her Master's Degree in Creative Writing in Edinburgh, Scotland. She has many hobbies, including painting, Muay Thai boxing, running, writing, and hanging out with her friends. She particularly loves traveling around the world and immersing herself in different cultures. She has traveled to 12 countries.

Sylvie Salib


I graduated with a bachelor's degree in Accounting. My love for children and my passion for teaching motivated me to change careers and earn my Montessori credential to become a part of the American Montessori Society (AMS). I am a firm believer in children's potential. I believe that the healthy development of children is crucial to the future well-being of any society. It is vital that children be offered meaningful opportunities to individually develop their potential, enabling them to step out into the world as responsible, engaged, competent, and respectful citizens with an understanding and appreciation that learning is for life.

Guiding children, playing with them and getting into their world have always been a source of joy to me. Over my 8 years of teaching different ages, I've learned that children are great teachers and amazing problem solvers.

I enjoy being with my family and friends, meeting new people, cooking, reading, traveling, learning something new, and enjoying all forms of arts.

Afsaneh Noorparvar

Writing Specialist

Children are one of the greatest sources of inspiration for Afsaneh. She believes that their sense of wonder and curious absorption with the world are sacred and need to be kept active. Acton Academy philosophy creates a framework to do just that and Afsaneh has enthusiastically found her way to our team.

She has a Bachelor's degree in English and a Master's in Education and she has spent most of her professional life in classrooms. Her purpose in the field of education is to be open to new ways of harnessing that sense of natural curiosity in children and directing it towards a lifelong passion for learning and development. Her focus will be mostly on our learners' writing skills at Acton Academy East Bay.

Amongst many things, Afsaneh particularly enjoys movies and arts, outdoor living, and socializing.
