Dr. Nguyen is a wonderful doctor. He is very thorough, reviews my symptoms and decides what the next steps should be in order to rule out any cancer. He recommends certain procedures and tests to make sure I do not have any other medical conditions. I am very happy with the medical treatment Dr. Sean has shown me!
