Conditional First and Last Dates

I have a worksheet containing contact dates for a list of supporters. I am trying to, in a separate worksheet, list the first and last dates that each supporter was contacted. So the source worksheet looks something like this:

id name date
11 Bob Smith 1/1/2007
11 Bob Smith 2/1/2007
12 Jane Jones 3/1/2007
12 Jane Jones 4/1/2007
12 Jane Jones 5/1/2007

And the destination worksheet has the following column headings

id name first date last date

I feel that I should be able to somehow conditionally use the id fields to fill in the first and last dates, but can't seem to get the formula right. I realize that the formula is complicated by the fact that the source data and the destination cells are on two different worksheets, but that is the way it has to be.

Any help would be greatly appreciated.
