Yeah, you need to get in touch with them first on the phone in order to set up an appointment. But I'm pretty sure they're taking new patients/customers...

I've heard another person on here say they had trouble reaching them too. I would suggest to continue to call occasionally. I've had trouble getting a hold of them once in awhile too. Let me know if you still can't get a hold of them in a couple days and I can maybe get in touch with them and find out if they're taking new patients.
