Excel 2003 Counting how many data cells correspond to a specific cell (Person's Name)

I have two columns. Column A has a person's name and Column B has dated notes on that specific person, some names have more notes than others. I was wondering if there is a function similar to count that could see how many note cells associate with a specific name or if you can look up how many dates appear for a specific person, thus giving you the number of notes on them. Any help or advice is greatly appreciated I have a thousand names or so with notes I need to count. Example I attached to this post.

Column1
Name

Durant, Kevin

Column2
Notes

3/8/12-Met with Kevin talked about blah
3/12/2012-Discussed procedures

Column3

Number of Notes
2
