I love Marin Horizon

I have had an incredible experience for pre-school at marin horizon. I have loved all my teachers and they have made my children love going to school. I had my daughter there for 3 years and my son there for two and they both have had great experiences and learned so much.

Love of Learning for Life!

My son just completed his first year at Marin Horizon and he (and I) couldn't be happier. He just turned 4 and has mastered the alphabet, can count and understand simple math, and is starting to sound out words. Besides these skills, their cultural studies focus this year was Australia. He can point out Australia on the globe and tell you about all the animals that live there. I am extremely pleased with the world view the entire school promotes. Their Earth Day celebration was the highlight of our year!

I am a working mom who doesn't have the time to drill with flash cards so I know I can attribute his learning to the amazing team of teachers at Marin Horizon. His head teacher has her Masters in Education and is a dedicated professional. If you are looking for preschool to be more than a daycare and a true foundation for a love of learning for life, check out Marin Horizon School.

Excellent preschool - excellent elementary school

We have been a happy MHS family for the last 10 years. All 3 of our children started in the Toddlers (2 year old) program and moved into primary and then elementary. Each year I am amazed at how engaged my children's teachers are and how they celebrate each child's unique learning style. While we originally chose MHS as a preschool, we were so pleased with the education our children were receiving, we decided to stay. I am very grateful for the love of learning that MHS has helped my children develop, starting all the way back in the preschool program.

Love this school

My daughter just finished her first year at Marin Horizon in the "toddler" program. I can't say enough good things about the school. It is a wonderful community with caring teachers and educators passionate about children and teaching. This year was all about learning how to get along with others and being in a school environment and she loved every minute of it. We are looking forward to watching our daughter grow at Marin Horizon.

Marin Horizon School

Marin Horizon School is a gift to education in Marin County.
We have two daughters that entered Marin Horizon in middle school (6th grade) and our only regret is that they didn't begin their earlier. The school provides a learning and social environment that truly values each child, teacher, administrator and parent in a kind and nurturing way while providing a strong educational background. We absolutely love the school and the way it has transformed our girls into strong self advocates, instilled a love of all school subjects and self reliance through the amazing outdoor education program. We can't speak highly enough of our time at the school and only wish that it continued through High School!
