T-SQL (SS2K8) :: Replace Multiple Characters With Single Character In A Column?

I am trying to replace all special characters in a column with one special character.

Example:

Table: dbo.Employee
Column: Name
Name
-------
edwardneuman!"<]
mikemoreno)'>$:
JeffJensen"?>"

I am trying to get the namepart to the left of ANY special character. To achieve this, I am thinking of replacing all the special characters with a single special character so that I can find the first occurrence of that special character and grab left of the special character (SUBSTRING/CHARINDEX). This way I don't need to loop through all the special characters.

I am expecting the following results:

Name
-------
edwardneuman<<<<
mikemoreno<<<<<
JeffJensen<<<<
