As Oprah's Big Give winds down to the finale of its first season (Sunday at 8 pm/ET, ABC), three philanthropists-in-training remain. We asked host and Oprah pal Nate Berkus to give us the lowdown (or in this case, the high points) of each of the final contestants, who will return to their hometowns for the final big challenge. Also, look for a special drop-by from Jennifer Aniston!

Dotcom entrepreneur Cameron Johnson
"Because he achieved financial success at a very early age, Cameron thought he had this in the bag. But giving back - using his incredible organizational skills and sales ability to help anybody else - wasn't part of his vernacular. Through the course of this show, Cameron has really come to understand just what giving is able to give back to you. He's one of the most tenacious people I've ever met, but has he thought 'big' enough every week?"

Beauty queen Brandi Milloy
"People underestimated her because she's pretty, and that worked to her advantage and to her disadvantage at different times throughout the show. But Brandi has proven week after week that she's also a very empathetic, very competitive and highly organized player. Her inner beauty has really shone through."

Businessman Stephen Paletta
"Stephen is truly one of the most compassionate men I've ever met. His strong point is that he was already devoting his life to giving back to other people on a daily basis. He captured me on the very first episode with how he and his team partner Eric (Klein) raised so much money for A.J., whose husband was killed on the job. Stephen has been really effective in the goal to help people but also in maintaining the spirit of the show." - Ileane Rudolph
