My doctor just had me treating at home and I did all my research online. There is a clinic in Atlanta that I think is referenced here on this thread in several places that specializes in the tDCS treatment. I think they also have an at home program where you travel there to learn how to use the machine, the protocols, etc and you will have them as a resource but then you continue treatment at home. They have also (I think) partnered with other physicians who were willing to assist with getting people started on treatment with tDCS. I did a search of "Atlanta tdcs clinic" and it popped right up.

Since I've been doing it on my own, partnering in the beginning with others who were using the treatment successfully, I'm not too familiar with the doctors who are using this treatment and the practice. But I would definitely recommend calling them and seeing what they have to offer or if they know of anyone else who is offering the treatment.
