Our son has developed into a young man over the two years he has been attending Mariner Middle School. The teacher and coaches TRULY care for the students on many levels, not just academically. That said, they hold the children accountable to make sure learning is taking place as they should. Our experience has been phenomenal and I would highly recommend Mariner.

My child has to come home and learn math on You tube. Complete strangers do a better job teaching my child than the math teachers .

I have never come across as many caring and supportive teachers in a building in all of my life. Teachers push and support students along the way and will always go the extra mile in order to help a student. With wonderful kids, amazing teachers, an excellent administration, Mariner Middle School is truly a great school!

The school is not very welcoming to parents and has a weak PTO. Usually only five PTO members at meetings, however, if you ever attend, you will see why. The school does have strong, highly qualified 8th grade teachers who truely love to teach.
