As a coordinator, senior language instructor, center head and a content writer the basic requirement at the DNA level was the same \u2013 effective communication. He discovered early in life that quality of communication makes the difference between great results and mediocre outcomes. And thus, he developed his first forte: focus on the listener and tailor the message accordingly.
