Dr. Leung has saved my life. I had such bad allergies that I was having anaphylaxis at least once a week. He is extremely knowledgeable and personable and he really cares for his patients.

Dr.Leung is an amazing physician. He is so knowledgeable. He is empathetic and truly cares about his patients. I’ve seen so many doctors around Boston. but I must say no other doctor cared enough to followup with all of my health-related issues but Dr.Leung. This important qualification needs to be remembered when choosing a doctor. I never had any problem with his staff. In fact, I had a great experience during my first visit because of a member of his staff. I remember very well how nervous and frustrated I was before my first visit. I was first seen by his assistant, a Lebanese doctor. His assistant was attentive, understanding and so empathetic. He reassured me that I was in good hands. After that I was seen by Dr. Leung, who was well informed about my symptoms. Dr.Leung has been following up with my case since then. He is knowledgeable, energetic, reassuring, and trustworthy. I recommend him to everyone seeking resolution to his medical issues.

My experience with Dr. Leung and his staff was excellent. They did a very thorough job of understanding my complicated medical history and symptoms. My test was very professionally done and I was confident that my result was accurate. Dr. Leung did an excellent job of explaining my condition and what the treatment would be. Excellent bedside manner. I would highly recommend Dr. Leung

I had been sick for about 10 days prior to seeing Dr. Leung and when he saw me, he immediately knew I needed quick medical attention and helped me get the right treatment & surgery asap! He has been a God sent because even when I was not able to hear back from Tufts hospital docs and staff, Dr. Leung kept checking in on my progress and recovery. I truly appreciate his quick diagnosis and attention to detail.

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!
