Dr. Leung is the worst dr I ever been to. No knowledge. He is very quick to dismiss your issues and ideas of what could be the problem since other test results are negative. He literally told me I should not have come to the walk-in regarding my issue and I should have went to my family dr. Keep in mind I was in pain and it was on the weekend. He is just another dr who cares about the money and not patients. He is worthless and an incompetent Dr. It makes me think he treats his "own" people with care but minorities with no care.
