In the founding years of San Francisco Schoolhouse, Rebecca Dake simplified the definition of an excellent education down to two basic ingredients: a passionate, experienced teacher, and a safe and healthy room. As Schoolhouse has grown over the years, we have assembled a team of multi-talented individuals who work in cooperation with each other and with the children and their families, sharing their passions and their vast experience with life, learning, and progressive education. Learn more about each member of our team below.

"As a teacher, I believe that teaching is not just about the educational benefits we give to students, but the social and emotional benefits as well. We as teachers should be instilling a life-long love of learning in our students. At this age it is so important for students to love, play, and have fun in the classroom, to set up their attitudes towards school for the rest of their life. I love being outdoors, which will be much more comfortable here in SF than it was in Texas! I am also a lover of the performing arts and have a major sweet tooth- I look forward to taking in the best performances and sweet treats that San Francisco has to offer over the coming years!"
