Diagnostically Trained (TFTdx):

Those practitioners who have completed diagnostic training are entitled to use the designation TFTdx.

Only those who have undergone additional training under the direct supervision of Dr. Roger Callahan are approved to train others in the practice of TFT Algorithms.

Voice Technology™ Trained (VT):

At the highest level of CT-TFT training, VT™ practitioners use a voice-based causal diagnostic procedure to offer individualised treatment for almost all psychological and some physical  problems. As all the required information for diagnosis is encoded in the voice pattern, it is possible for treatment to be completed in the course of a telephone call from anywhere in the world.  VT practitioners are also approved to train others in the practice of TFT Algorithms.
