Voice Actors of Gym Leaders

[PAK Man]

I'm trying to identify the voice actors of some gym leaders. I've figured out a lot of them, but there's a few I still haven't figured out. I have a list below of the ones that are either unconfirmed or unknown altogether.

Koga - Ken Gates or Stan Hart? (both were posted on Wikipedia, but Gates has been removed. I can see it as either one)
Cissy - Lisa Ortiz? (from what I remember, it sounded just like her)
Morty - Andy Rannells? (he's rumored to have done Morty's voice, but I don't think he worked for the show at that point)
Jasmine - Megan Hollingshead?
Roxanne - Amy Palant? (again, I'm not sure if she worked for the show at that point.)
Brawly - Jason Griffith? (see above)
Tate - Jason Griffith or Andy Rannells? (I've heard various people say it's Griffith, but Rannells was credited in both episodes. This also happened with Liza and everybody saying Amanda Brown did her voice, when it was actually Andi Whaley)

UNKNOWN:
Danny
Luana

Just wondering if anybody knew about these voices.

Morty - Andy Rannells
Roxanne - (whoever did Ishizu in YGO, I think)
Brawly - Jason Griffith
Tate - it wasn't Rannells, I'll tell you that much.

Tate is DEFINATELY Griffith, I can recognize his Sonic-voice miles away.

Lt. Surge was Maddie.
Juan was Sean Schemmel.
Brawly, without a doubt, is Wayne Grayson.

Brawly, without a doubt, is Wayne Grayson.

I'll contest that. =O The heck he wasn't. Brawly was Griffith.
