If the excessive load time or the errors in functionality are because you're tweaking it right now, can you please re-post when the site is actually available to be viewed?
Otherwise, Safari 3.0.3, OS X 10.4.10...
Orange oval - This section just lacks cohesion... it seems to be a bunch of randomly thrown in icons. Your practice name is quite possibly the least prominent thing on the entire page.
Pink oval - this is how the menus look. Here's another example:
Blue oval - what is the purpose of the little icons following every link? They appear to be intended as some sort of visual cue, but they're not used in the standard way that icon is used elsewhere, and follow every link, seeming purposeless.
Green oval - There's an odd stylistic jump here. I don't understand if this is what you intended.
Red ovals - White space between paragraphs would be good.
When this is moused over, the entire thing gets underlined, even though there appear to be individual links for each item.
Hope some of that is helpful. Overall, I like the core design motif. I think if you uncluttered it substantially, the fonts, color scheme (excepting that I think the blue is the wrong highlight color), and some of the visual elements are excellent building blocks.
