Of the four you mentioned, Vic's the only one I know off the top of my head who has done voice work for both LA and Texas. I don't recall any Funimation or Sentai works Crispin, Yuri, or Steve have done.
Ron's SSN (I think it was Ron's) was purely the fault of the court. They're supposed to redact that information, but whoever was writing up the docs done goofed.
Steve has done alot for Funi, but I wouldnt call it his home base. Isnt he LA-based?
Crispin Freeman voiced Alucard in all Hellsing releases. Including Ultimate, which was a Funi project IIRC. He also reprised his Zelgadis role in the Slayers franchise for Revolution and Evolution-R, but to be fair, I'm actually not sure if he worked for Funi or Sentai at the time. That was during that confusing time when ADV became Sentai and Funi bought a lot of their titles.
As for Lowenthal, he was Sasuke in Naruto, which is a Viz property, as well as the main character in Gurren Lagann. I know Funi had the rights to the show, but maybe they got the rights later on from Aniplex? I legitimately do not know, I am recalling stuff off the top of my head that I could be misremembering.
What I do know for a fact, is that the Texas clique, for the most part, stays in Texas, while the rest of the VA scene is more keen on movin' around.
And IIRC, JosephTX doxxed his SSN on here, but it was already made public, am I right?
