TFT-VT

I got the opportunity having the VT training with Dr. Roger Callahan and a new dimension of TFT was revealed to me. I will use this opportunity to thank him for his discoveries and his non-resting work developing TFT and sharing this marvelous tool and his knowledge with me. I would also like to thank Joanne Callahan for her support and enthusiasm that I will bring with me in my future work.
