But now Toth, 40, is getting a whole new level of recognition as the tall, handsome man who is engaged to Oscar-winning actress Reese Witherspoon.
Here is a closer look at Witherspoon's new leading man.
1. He's a Hard Worker
Like many agents, before he was promoted, the ambitious Toth started in his agency's mailroom, making deliveries and running errands. "I think I may have bought fruit for the entire agency on a daily basis," he told The Hollywood Reporter in 2004. Later, he started working with such clients as Forest Whitaker, Scarlett Johansson, McConaughey" and Rachel Bilson. Says a source who knows Toth, "He has a great head on his shoulders. He always sees the big picture and he's so level headed. A lot of people look up to him."
2. He Is a Lion at Heart
Toth is a graduate of L.A's Loyola Marymount University (Go, Lions!), where he graduated with a major in political science. While there, he was a member of LMU's 80-year-old service organization, the Crimson Circle.
3. He's Good with Witherspoon's Kids
Once the couple had been dating several months, Witherspoon felt comfortable enough to introduce Toth to her kids, Ava, 11, and Deacon, 7. "He's very down-to-earth and great with her kids," a friend said at the time. "She wants Jim to be a part of her everyday life with the kids and they've had a great start together." Since then, the couple have been frequently spotted happily out with her children.
4. He's a Guy's Guy
His date may be famous for her chick flicks, but Toth prefers more manly entertainments, telling The Hollywood Reporter that his favorite all-time movie is The Godfather: Part II, and TV show is Miami Vice.
5. He's Ready to Settle Down
Once known as an active dater, Toth was often seen out and about with his famous friends and clients. But after several months of dating Witherspoon, a source close to the actress told PEOPLE of Toth, "He's more mature and in a place in his life where he's ready to settle down." The source added that Toth and Witherspoon met at the right time. "Sometimes in your life you meet someone who is ready to move in the same direction as you. You're on the same page and you're moving in the same direction and everything feels just right," said the source. "That's what happened with Jim. He was ready to take it in this direction and she was ready to follow."
