$dr = qr/(?:dr\.|doctor)/;
$gn = qr/(?:condoleeza)/;

/
  $dr \s+ $sn
  |
  $dr \s+ $gn \s+ $sn

  $gn \s+ $sn
/x

which can be simplified to:

$dr = qr/(?:dr\.|doctor)/;
$gn = qr/(?:condoleeza)/;
$sn = qr/(?:rice)/;
/(?:$dr (?:\s+ $gn)? | $gn) \s+ $sn/x

Don't forget to escape the . in dr. to dr\.!
