My son is currently being treated for acne by Vivian Tam. For years, my son was on mild anti-biotics for acne (not roaccutane), and all the usual acne treatments available from the pharmacy. We tried just about everything. And then it occurred to me to try Chinese medicine. He is now on herbs which have improved the condition out of sight. I can't speak highly enough of Vivian. She is professional but very warm, knowledgeable and easy to talk with. We are extremely happy with the huge progress to date, so I would definitely recommend Vivian.
