Both of my kids go to Happiness Hill and we are beyond happy with the school. The teachers are amazing and loving, the environment is safe and quiet.
Kim Nguyen · 5/5 on Google · a year agoMy 4yo has gone here for past 3 years. It's terrific. The teachers are very warm and caring. My child is very well behaved and recognizes all of her letters and numbers. She is starting to read short words. I wish I would've known about the school with my first child who is now in six grade
