Not sure if this doctor is a misogynist or simply thinks he is better than everyone else, but I have not been talked to by any care provider with such condescension, impatience, or rudeness in a very long time. After I told him I had a recent head injury, he accused me of not listening, complained about how much time I took, dismissed the skills of every other practitioner I had seen in recent years, dismissed every piece of recent advice I had had, and took every opportunity he could to indicate that I was an idiot, and would not let me say anything or correct misinformation about my file that he said out loud without accusing me of interrupting him. His admin also clearly is unhappy in her job. Only the nurse there was very kind caring and friendly. Maybe he is smart, maybe he knows what he is doing, I don’t know. But not sure it’s worth being treated so badly to see him.

Dr. Lee rushed me in and out of his office. I have had sneezes that lasted longer than the appointment. He did not provide more than the bare minimum information in response to my questions and I had to ask him about my allergy testing that his nurse performed, He absolutely did not review the 3 page patient questionnaire that I diligently filled out, and had sent back to the office a week in advance. If you are looking for a doctor to speak with you with any interest or empathy, go elsewhere.

Been my Allergist for 4 years and totally useless. Shameful.

I always leave feeling good after speaking with dr lee. Like there is a plan. He has a great conversational style that is informal and makes me feel heard and alleviates my anxiety. Very down to earth while at the same time professional with light humour. I have also seen him deal with an emergency and he was super calm collected. It gave me confidence that I’m in good hands.

Listens to patients and truly wants to find something that will help them. An inquisitive mind. Highly recommended.

From booking to seeing by far the best experience I had with a doctor. Plainspoken and well explained.

World famous doctor in his field and it shows. I researched doctor Lee prior to seeing him.

Dr Lee is amazing. I can say he changed my life. My life has improved so much with control of my asthma and eczema. Through the years he’s been able to address small things here and there that have come up. Knows more than my respirologist and dermatologist about my conditions. One thing others have commented on and noted is that Dr Lee is exceptionally good at explaining and educating. He is also somehow extremely knowledgeable about everything. My partner and I both see him now and sometimes just talking to him makes you better.

I used to fly in once a year from Australia and began seeing Dr Lee since 2013 prior to the pandemic. My case is complicated and I can’t access the medications I need in Australia. Dr Lee went well above and beyond to organize with a pharmacy the medications I need. I’ve seen 4 specialists all over Australia for the same condition. Dr Lee is extremely straight forward and cares about helping you with the best meds. I was advised to take cyclosporine in Australia that no one wants. No thank you. He now has been starting a medication that may cure this thing once and for all. I’m super excited. I also learned that Dr Lee is the first doctor in the world to come up with this idea. He’s all round brilliant.
