I just poked around the website a bit too, and personally, just from my impressions from the website, this is a school I would avoid.
I know, this isn't really a fair judgement because I don't actually know these people, but it is my opinion based on how they have presented themselves in the website.
First off, they list some of their training background, as well as who their instructors were. However, they never indicated that their instructors gave them permission to teach. Instead, they point out that they hold rank thru the Ultimate Black Belt Test, at 5th and 3rd degree for him and her. But this is no indication of their true understanding of the arts that they studied and now teach. Perhaps they are good, and their instructors actually gave them permission to teach. Perhaps they are not, and never received such instruction. Perhaps the Ultimate Black Belt Test is how they have decided to circumvent their real instructors, and gain a "credential" from an outside source to justify teaching. But the guys who administer this test know nothing about the arts that the Pasquales have studied, and are not in a position to give them teaching permission, as they were never the Pasquale's instructor in the first place. It's just really a lot of smoke and mirrors.
Secondly, their website just sort of shouts "commercialization!" They've got testemonials, and some sort of survey voting them "best martial arts instruction" and stuff, and again, this just comes across as looking for validation from outside sources. If their instructors had given them permission to teach, then they don't need outside validation of what they are doing.
Bow Sim Mark is listed as one of their teachers. She is kind of famous in the Tai Chi Chuan world. It would be interesting to know if she, and their other instructors, have granted them permission to teach.
