Dan Gordon, Dan is Leo's competitor for Piper and lives next door to the Halliwells. Dan used to play baseball for the Seattle Mariners but now lives in San Francisco with his niece and is a construction worker. He is always trying to find out bad things about Leo to try and win Piper back. Dan doesn't know that Piper and her sisters are witches and that Leo is a whitelighter. He's practically just your nosey neighbour who is looking for love in the wrong family.
