Error message on public site AND admin page

When I attempt to access our public site (http://infocusradio.com) or wp-admin, instead of seeing the pertinent page I see a blank white screen that simply reads:

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /home/content/03/12122203/html/InFocus/wp-config.php on line 83

How do I resolve this???
