I would not say to rule out a practitioner because they are still detoxing. The ones trained under Dr. Wilson and who still work under him are required to remain on the program and do regular hair tests. Unless they have been doing this for many years, they are technically still detoxing because it takes years for most of us to get healthy. Eileen Fang who is in N.J. and is listed on his site seems excellent. She moderates a FB group for those of us who are doing NB. She is no longer working under Dr. Wilson but was trained by him. I find her to have a lot of wisdom and knowledge about NB. And she would tell you that she is still detoxing. But is obviously healthy enough to work and help others.
