As always for over 10 yrs, he's all ears to your complaints and always try to resolve your issues even though you're taking up his time for his next patient.... unlike other doctors who makes you aware that his next patient is up so you have to hurry up. And he's open to alternative treatments as long as it's medically sound, and he would provide guidance and check up. Best doctor my husband and I have ever had.

A responsible and attentive family doctorI had an excellent experience with Dr. Leung. Because of his thorough examination and attention to detail, my cancer was detected early and successfully removed. He addressed all of my concerns in a courteous and professional manner, and I always felt heard and cared for. The nursing staff was also polite, supportive, and professional throughout my visits. I am truly grateful for the care I received.

A great doctor with an apparent easy-going relaxed nature that puts me at ease (I'm not good in a medical environment) , and I like the fact he prescribed medicine that would quickly get my cholesterol/blood-pressure issues under control while the long-term plan was diet & lifestyle changes that would enable me to stop taking medicine .
