First off, with the changing main images, the changing quotes, and the changing "success stories", there is too much activity on the main page .... it`s hard to focus or see where I want to start with everything changing every few seconds. Other than that, it looks very informative and positive.
Your "h" tags are present, but not utilizing keywords that would be effective, and you need unique page titles and descriptions for more effective SEO.
