When I went in to see Dr. Leung I felt incredibly rushed and it did not seem like he cared. He also prescribed me expensive medications that my insurance does not cover. Save yourself time and go elsewhere.

I probably wouldn’t return. I had some medical concerns and I knew that identifying as a member of the LGBT community it was important for the physician to know about about this. I felt that the bedside manner was poor and honestly felt like I was being shamed for my sexuality. He is a knowlegdgeable Dr I just wish he was more professional with the way he words things.

Dr. Leung was very experienced and sure of himself. His confidence and attentiveness made me feel heard and reassured me that I was in good hands. He got to know me as a person and I got the sense he cared. Even when there is no action to be taken, he finds the time to stay and chat for a while!

I did my immigration medical exam here. The visit itself cost $180 and does NOT include any of the required lab tests. That's just the amount the doctor charges to fill in the form. I have already paid over $400 out of pocket, and just got another bill from my insurance company claiming that I owe another $350 for lab tests. This is ridiculous. USCIS accepts both skin tests and QuantiFeron for TB, and skin tests are generally much cheaper. Dr. Leung does not offer it as an option at all.

Fantastic! He was prompt, helpful and incredibly knowledgable. He shared information at our level, not way over our heads and not too dumbed down. We were able to get a quick appointment which was incredibly helpful AND he is open on Saturday!
