Hi Linda,
it would be nice to put in some paragraphs on the homepage, the text block is too long without breaks in it.
In "About Us" you write I and me and then us. You need to decide which one you want to choose, but you can't have both.
No indent under the mission statement as you haven't use any before. Just put it in line with the other text.
The layout is nice and clean, but so far the website lacks a bit "personality", but I'm sure you will change that soon.
