Dênis was discovered by Santos when his team Ipatinga eliminated them from Brazil Cup on penalty shootout, in 2006.

He conquered the right-back spot and played well in 2006 until a knee injury knocked him out of the season.

When he recovered, already in 2007, his spot was covered by new signing Pedro.

When he finally displaced Pedro (who ended up being released and joined Sporting), he injured himself again against Caracas FC.
