My 5 year old is about to start his 3rd year in a Montessori school and my 3 year old is starting his first year. I love the Montessori method of teaching. Neither of my kids have learning issues, but it the thinking behind Montessori is so intuitive with respect to how kids learn. I have been very happy and very impressed with what my son has learned in school. You definitely need to look into the school and ask around about that school's reputation and make sure they have a teacher there who is able to handle your son's learning issues. Any school can really call itself a Montessori school so you need to make sure the teachers are Montesssori trained and that the school has some sort of Montessori certification and then ask for feedback from people who go there.
