Are your templates mobile-friendly?

Hi, I hired a word press programmer to build a site using your templates and plug--ins and he says that your templates are not mobile-friendly. Are your word press templates mobile-friendly?

I need something simple like this:
http://americancognitivetrainingassociation.wordpress.com

But we need it with a membership sign up and dues management functionality (we're building an association and don't need social networking functionality (such as profiles and messaging) as well as both public and private content.

Do you have a template that is both laptop and mobile-friendly?
