On the front page "provide highly personal services such as:" is slightly blocked by the picture, and it overlaps the top of the text on the next line.
On the Boarding page, "Barn Rules and Guidelines" overlaps the next line. Once you decide on boarding price are you going to list it on your site? Or a price range, depending on amenities chosen by your boarders?
On Training, there is some text near the bottom (it starts with "You can view other") that overlaps some other text and makes it impossible to read. And the last line at the bottom of the page is cut in half by the black border.
On Lessons, the picture obscures some of the text. The link at the bottom is covering some text.
On Local Hauling, the large text "Local hauling" is overlapping some of the text.
That's enough to leave you with for now
. I haven't looked the other pages yet.
By the way, you have some gorgeous horses on your site
. Good luck working out the bugs.
