Hello,
If you are looking for training in Teradata DBA or Dev, I suggest to take the classes from Manohar. I am attending the training from him. He explains each and every topic very clearly and has indepth knowledge in the subject. He answers all the questions asked by the trainees by listening patiently and answering them .
If you are interested reach out to him @sunmanu9@gmail.com
