After having Salle being tutoring my two kids, my children started having 'A' s in reading and writing in the school. Salle is very patient. She works with kids in a way that my children like. She also teaches good manners. My children treat her as part of the family now.
My son is finally getting the concepts of Calculus 2. He misses a lot of class due to his athletic schedule, so this has been very helpful.
