I'm no where near you (over a big ocean), but have you checked the Dermaroller website? That might be the best place to start:

www.dermarollerus.com

The Aussie version has a clinic finder but I can't see one on the US website. There is a contact option though, you might want to ring or email them for the clinics closest to you.

Good luck!

I'm from Iowa, and I can tell you the closest I was able to find anyone was Chicago.
