I know three of these peeps... All good anime: Natsu from Fairy Tail, Nagasumi from My Bride is a Mermaid, and Karou (one of the twins from Ouran high school host club). The thing about Todd Haberkorn is that you can tell it's his voice, but it varies so much it just works. He's also a huge nerd so that's a plus~
Although the more recent releases of Fairy Tail in the West have been focusing on a filler arc, FUNimation has already announced the English voice actors for two important characters that will appear as enemies once the series returns to the canon storyline with the beginning of the Grand Magic Games. OH YES
J. Michael Tatum. This guy does some amazing character voices. My personal favorites are Sebastian Michaelis from "Black Butler", Kraft Lawrence from "Spice and Wolf", Kyouya Ootori from "Ouran High School Host Club" and Shizuka Doumeki from "xxxHolic", Rintarō Okabe from "Stein's;Gate".
