Welcome to The Montessori School at Lone Tree


For over 30 years, The Montessori School at Lone Tree has nurtured children to grow into students with a love for learning and deep respect for life. Our school is knit together with experienced faculty and invested parents creating an extraordinary community dedicated to Montessori principles.

One of the unique characteristics of The Montessori School at Lone Tree is the quality and expertise of our teaching staff and administrators. Our teachers are committed to the Montessori philosophy of education. As such, their strongly held beliefs in the capability and dignity of each child lead to a learning community based on respect. We have a broad diversity of our community and we are proud to be a school that makes every person feel welcomed and appreciated. It is an environment characterized by cooperation, collaboration, kindness, and a sense of purpose.

Our school is year round. We start when children are 2 & 1/2 and fully potty trained and goes through kindergarten or 7 years of age.

Hello MSLT Community!

We had our Board of Directors meeting on Friday afternoon and we discussed the masking policy of MSLT. After careful consideration, we will allow our parents to decide what is best for their own child and family with respect to masking their children or to choose not to. Your children are in a critical period for speech formation and language. Children are also learning how to read non-verbal cues from their teachers and classmates. Masks make this learning and growth difficult. However, we also strongly support the parents’ right to choose to mask their children and encourage them to do so in the context of the evidence and their own personal situation. In either case, we will get through this next phase together and I trust you will make the best decision for your child.

Although all of our teachers are fully vaccinated, I will ask the teachers that can wear masks to do so when they are working with the children. Some teachers have underlying health issues that preclude them from wearing masks full time. Some children will not be able to wear a mask and not all the time. Obviously, during meals and rest time, masks will not be allowed.

We are not co-horting the way we did last school year. For instance, the kindergartners throughout the school are together in the NW classroom in the afternoons and the Pre-K children throughout the school are in the SE classroom in the afternoons. The north and south nap rooms will remain separate. North and South Full Day (All Day) children will meet on the south playground after the teachers take roll in their respective classrooms and reapply sunscreen. Parents, please remember to sunscreen your children before school every day. Thank you for arriving promptly at school no later than 9:00 a.m. It makes a difference!

I have signed our school up for the free Covid testing that Governor Polis implemented. We are supposed to have a meeting to talk about logistics, but I have not heard when that will be yet. I will continue to be transparent with you and be as communicative as possible. I appreciate all of you that have reached out to me in support during these difficult times. I love that you trust that I will always put the children, our families, and our staff at the forefront of every decision I make. I cannot make everyone completely happy and I have accepted that. It is difficult for me. However, the pandemic has caused me to get much tougher skin. I understand that you want what is best for your own child and I respect that completely!

As we start having masks again at MSLT, the teachers will keep you abreast of how your child is handling it, as well as the class as a whole. Thanks again for being proactive with keeping our children and community safe.

With Best Regards,
