I would say that Dr. David Tzang is a very calming man, who when telling you something not so good, tells you in plain speech. If you are told medical jargon, you soon forget everything,but, Dr.David Tzang put me at ease, and I don't feel scared or worried anymore. If you find yourself under his care, I would trust him fully. Tricia.
At a very scary time he was confident, reassuring, honest and above all - positive and energetic. Quite aside from his skills in oncology it was his personality that helped me to survive. I would not hesitate to recommend him.
