Montessori Alumni Quotes:

"The Montessori method—learning by doing— once again became my stock in trade..." from Personal History by Katharine Graham

"Montessori taught me the joy of discovery...It showed you can become interested in pretty complex theories, like Pythagorean theory, say, by playing with blocks. It's all about learning on your terms, rather than a teacher explaining stuff to you. SimCity comes right out of Montessori—if you give people this model for building cities, they will abstract from it principles of urban design." - Will Wright, designer of The Sims

“I really enjoyed the Montessori method. I could grow at my own pace.” - Sergey Brin, co-founder of Google
