It looks like you are looking for 2020-2021 so perhaps this reply is not too late. Our two children attended Ridgemont Montessori School and we cannot say enough about the Montessori environment, the teachers, the families. It is an oasis in McLean and Ms Button and Ms. Molina and Ms. Luz have been absolute gifts to our children. Our children learned at Ridgemont how to be thoughtful, independent, curious and respectful of others. Many parents attended Ridgemont when they were children and come back for their own children, which is telling about the quality of the education and care for the children. Students who graduate from Ridgemont head into public school, area private schools, or Montessori elementary schools (e.g., Full Circle Montessori). Make sure you schedule a time when you can observe the classroom environment. It's almost magical to see the teachers guide these small children. Ridgemont is where teachers studying to become Montessori teachers observe and train. If you are committed to Montessori, I encourage you to check it out. Good luck! What a fun time for you and your family.
