How unfortunate that the other parent had such a bad experience! LTA is one of the best in the area. Your children will thrive in a structured environment where discipline is a must. The directors and their staff are incredible and care for our children. Their curriculum is excellent, and the kids are extremely well prepared for kindergarten (many end up in the gifted and talented programs). 2 of my kids went there, and I am so thankful that I found LTA. Let's not forget how clean this place is.
Again, if you want your kids to learn in a structured, clean environment, where respect of the teachers and other kids are important, this is the place.
