Website Organization

In thinking through the interface of our new site, I am trying to clearly define how users will navigate our webpage. Generally speaking, we will want to give visitors an INTUITIVE experience, a CLEAN and UNCLUTTERED interface, and to navigate with as FEW CLICKS POSSIBLE to get what they want.

Often times this is easier said than done. Below is an outline of what I am initially imagining. I know this is a busy time in the term, but if you can shoot me any feedback about how to organize our information on the site based on the image below, it would greatly help me. Each tier of the below image would be available per click. So intially they can choose from "The Collaborative", "Accomplishments" and "Vitals". Clicking on each of those would move to the next level of detail, etc.

I'm eager to hear any thoughts...
Thanks all!
