The navigation and dropdown menu is great.
My suggestions:
1. Add a mission statement or slogan at the top. There is a lot of text and many people are not going to want to read all of it.
2. Reduce the image sizes. They are currently very large and take a long time to load.
3. Change the photo in the banner above the navigation or do some touch up work. It's very low quality and is very large. Because such a large photo loads in such a small space, the composition is way off so the kids are being cut off.
4. The orange is a bit dark. And you might try a
light yellow because it's is a happier color. Orange just makes people hungry.
5. If you can add small thumbnail photos of the people in the testimonials, do.
6. Change the logo. Artwork that is done in paint tends to be pixellated and low quality.
7. People love videos. Put the video on top of the text on the home page. People will eagerly click a play button before they read.
I hope that helps!
