OSM has a very positive learning environment. In the Pre-Primary they learn all the typical 123 ABC stuff but really focus on life and social skills. I've been very impressed by how much my daughter has learned. They have made cleaning up fun. She has also learned to enjoy being helpful. I've seen a great improvement in her ability to play independently. It's wonderful that they go outside everyday, unless there is extreme weather. They encourage a love of the outdoors and allow them to get dirty. They dig, plant and grow plants, collect acorns and leaves and have lots of fun in the snow. I was hesitant to visit the school after reading negative reviews about it but I realized that those were from a few years ago. I believe that they must have made some changes since then as I haven't had any bad experiences with the staff. I've only had positive interactions with the administration. They really care about delivering a quality learning experience. One of the most convenient aspects of the school is the curb-side pick up and drop off. It removes most of the odd separation form parent and transition to school issues. I rarely see any tears at pick up or drop off times.

As both a grandparent of students now attending OSM and an educator with 39 years of experience in the field of education, I am beyond thrilled that my grandchildren are attending Old School Montessori. Their open door policy is refreshing and I am able to stop in frequently to observe my grandchildren in their classrooms, both primary and elementary. I have also spoken to parents of former students who are now in college and they have nothing but positive things to say about their children's experiences at OSM. I have read all of the other reviews on this site and hope that all prospective families will make their own judgment about OSM. I highly recommend this school.

We have been very pleased with our experience at Old School Montessori. Our children attended OSM from 1st through 6th grades (our younger child is finishing 6th this year), and they have been excited to come to school every day. The teachers and staff provide a caring, supportive environment that allows students to learn at their own pace and promotes kindness and respect toward others. Our children have been challenged academically, learned to manage their time as they worked to complete assignments, and also developed great public speaking skills. Our children also loved programs such as Nature's Classroom, band, and Spanish. Our older child transitioned from OSM to middle school and high school without any problems, academically or socially. At the end of 8th grade, she was named the top academic student in her class of 380 students. She was asked to be the student speaker at the 8th grade graduation ceremony and spoke confidently to an audience of more than 1,000 people. We credit OSM and its dedicated teachers with fostering a love of learning in our children and helping them become more caring individuals. We highly recommend OSM to all families.

We have two children going to OSM (3 and 9 years old) and could not be happier. The life skills, communication, problem solving, conflict resolution and basic education are incredible. My 9 year old has made amazing friends (sleep overs, etc...), and having a parent group that is active in everything, even providing after school specialties (occasionally will have things like 3D printing class, LEGO programming class, etc...) has been wonderful. Highly recommended, and a great alternative to some of the failing school districts in the area.
