I had a similar situation for my 3 summers while going to school. Worked for the same company, each year doing something a little different.

I ended up doing a chronological resume, with latest employer to last. Summer employer was grouped into one.

Went something like this.


2005 - 2007 Employer X
- Did this
- Did that

Summer 2005, '04, '03 Employer Y
- Did this
- Did that
- Also did this
- Don't forget this too

2001 - 2003 Employee Z
- Did this and that

edit: I guess it's not as similar, since you probably worked between the period, as if I would have worked while going to school. In that case, probably would have looked like this. (For example, worked between summer 04 and 03.
