Remove duplicate rows in Excel, merge data in other columns

I want to go from this:

Name Email Birthday Visit Recall Postcard
Andrea x
Andrea x
Andrea x

To this:

Name Email Birthday Visit Recall Postcard
Andrea x x x

Basically, I have an x under the email, birthday and visit columns all for Andrea in three rows.
I want to remove duplicates and have the x's in the email, birthday and visit columns in one row.
