SQL Results horizontal

I found this sample online:

DECLARE @id_list VARCHAR(MAX) --varchar max works for SQL 2005 or above
 
SELECT @id_list = CASE WHEN @id_list IS NULL THEN CONVERT(VARCHAR,column1)
            ELSE @id_list + ',' + CONVERT(VARCHAR,column1) END
            FROM table1            
SELECT @id_list



which works great to display a single column horizontally but I need to display one column normally with the results of another horizontally:

Bob smith  |  09/12/2011, 09/13/2011, 09/15/2011    

in that example all dates with the name value bob smith.
