When Dr. Romano approached me with an idea for offering his DAT course and other science materials online I seized the opportunity. I began working closely with Dr. Romano at his tutoring institute, Romano Scientific, in Staten Island, NY and it soon became apparent to me that those students who followed his guidance and studied his materials reached great success.
