Fred

Fred is a friendly NPC who can be found in north area of House Jorasco, just in front of The Dead Halls (Dead Predators quest). He can respec the feats you chose while leveling up, as long as you bring him an appropriate Siberys Dragonshard and money to cover the expenses. You need one dragonshard for each feat being respecced, and this shard varies depending on your character level. You are allowed to swap one feat every three real-time days.
