    Great school. I have children that attend here and they love it. They are doing very well academically. Students that have graduated from here always say how well prepared they were when they attended high school. The overwhelming majority of our graduates go on to college. This is direct reflection of how well this school is preparing its students academically socially and spiritually. This school has a very loving environment and is very accepting of all students and parents no matter their background. You will never regret enrolling your child here at Old Mission Montessori School.

    We have two children at OMMS. We absolutely love every teacher that they have had. The class size cannot be beat and the community among the different ages is wonderful to see - it is great to have 8th graders as mentors to elementary age students as they really look up to them. I personally appreciate the attention that my children have received as far as what they specifically are learning. The curriculum in the classroom is not static but something that each teacher focuses on for each individual child. I love that my first grader is in a class with second and third graders. In a subject where they excel they are able to work on higher grade level material so that they are never bored or sitting around waiting for everyone else to finish. This is a small school and with it come the challenges of a small non-profit school. It is not all about the money (in my opinion) but parents are expected to help with things like fundraisers and school events and that is the case with any school. The fact that the office staff principal and many teachers know all of the students by name as well as the parents by name is nice. I highly recommend taking a tour of the school.

    My two children started at OMMS this school year and are thriving!! We could not be happier. They are in the preschool and have grown by leaps and bounds--more confident independent making friends and learning. It's so much more than "daycare". The approach works! And the teachers are fabulous and very dedicated. They have music and crafts as well as outdoor environment in their daily activities. The classmate are well behaved and the parents are involved and welcoming. We highly recommend this school.

    Love this school beyond words. I love the small class sizes the individual attention and the after school programs offered. My children have been here for four years and it is a good fit for us. The price for their education is spot-on and the teacher's have a great heart with a desire to help them grow in so many different ways. Catholic AND Montessori; you can't go wrong!

    I have multiple children at the school. My children have been at OMMS for almost 10 years since they were 3 years old. The academics and community are unparalleled. The children are able to develop a confidence and social presence only a smaller school could cultivate. My children feel at home and can academically compete far above their grade level.

    Not worth the money. Poor academics and poor discipline policies. It's all about the money. Most of staff is nice.. Other than that . You are looking at a School which takes kids in just for the money. Poor academic scores. In part by staff not having the education needed to teach . Lots of special needs kids without any staff able to Provide appropriate education .

    I can not say enough good things about our experience here. The teachers and administration are wonderful. We have been attending here for over 3 years (Pre-K and Kinder) and have been extremely happy with the educational as well as the social aspects. The sizes of the classes are small and my children are well above many of their peers when it comes to reading and math. I cant speak to the middle school but I am happy with the Jr Elementary as are the parents I know who send their children there.

    To sum it up this school as a whole is priced high for the value received. My son in preschool learned how to read so as for the all-day preschool I would highly recommend the PRESCHOOL ONLY and as a huge plus the preschool teachers are very loving! As for the upper grades St. Patrick or St. Mary are better schools and if you take your child on a tour of all three this school will be the last on their list and yours too. Take a look at the test scores. This is a good place for higher maintenance/needier children to get individualized attention. The pre-school and Kindergarten financially support the upper grades. The Parish is badly in disarray. The Camp Pendleton Soccer Mom parents are running this school be prepared to honor them and their ideas or suffer the consequences.

    Fantastic school very pleased with the nurturing teachers facilities and activities it offers. It truly has been a Godsend to my family's chaotic schedule. Daughter has done tremendously well not even 5 yet and she's already reading.

    This is a wonderful school. It provides loving and nurturing family environment. It's a great alternative to a "cookie cutter" public school education. The teachers clearly care for the students well being and strive to tailor their lessons to their ability. The Montessori aspect allows the child to makes choices throughout his day rather than being instructed to do each task. Also the curriculum includes a lot of variety which keeps my child excited and interested in school which is the most important thing to me. He is exposed to animal plant history and art studies and sees the world around him as a classroom. This school truly inspires a love of learning and I am very pleased with my son's education.

    Great School I love this place faith builds here. I am a student there and have been having faith problems. OMMS really helped me and now I alter-serve all the time in school and parish masses. I do have a few things I don't like about this school though. The after school sports are not held often all that happened last year was volleyball and soccer for the girls. -(. I am very into Montessori learning and didn't really receive that in 4-5th Grade. Many good things happen at OMMS though like the teachers are excellent the principal is very smart and KNOWS what she is doing and the academics are very difficult but not too difficult. (No mom didn't make me write this this is all me.) I am amazed at how well I fit in so fast everyone had such big warm hearts. Overall 5 stars.

    OMMS has great potential but lacks leadership discipline and skilled staff for a diversified student body. The campus is beautiful but the facilities are not well maintained. Parents are too involved and meddlesome in classrooms.

    This is our first year here. Our child is in the 4th/5th grade class. The warmth care and values at this school are wonderful. It is really a family environment. Up to 3rd grade is a more pure Montessori environment. After that they start transitioning the kids into 'regular' school style. Generally class sizes are small with lots of attention. There are some afterschool sports but it's limited if that's important to your family. Every grade studies foreign language! Full-time Art and Music staff. Again this school is small caring and packed with good values.

    My children absolutely excell in the environment at OMMS. They are getting a well-rounded education and are very comfortable in their surroundings. It is a small school with lots of attention to individuals

    The school is detrimental to students who do not fit their idea how children should learn. The teachers and administration lack the background and education to deal with student needs.
