Dr. Tun is actually an old friend of the family, so I have a personal opinion of him. I suppose that also means that I am probably the teeniest bit biased, as it is hard to be completely objective about someone who is a friend. But, I will do my best. As a doctor, Dr. Tun is completely professional and very concerned. I know he thinks very highly of his patients and his main focus is on healing people, not the money. On a personal level, he is a friendly and gentle person that is a good listener. He is a skilled general practioner and is very intelligent.
